• D Signs & Awnings · 4.8★ · Sign shop
• Signarama Willow Grove, PA · 4.9★ · Sign shop
• GOLDEN FOX SIGN · 4.9★ · Sign shop

If by “best” you mean strong commercial capabilities, broad service coverage, established track record, and ability to handle projects from design through installation, these Pennsylvania companies are worth putting on your shortlist. I’m not ranking them overall; the right choice depends heavily on the type and location of your project.

• Elmark Sign Company — West Chester
  Full-service commercial signage, including illuminated/channel letters, monument signs, dimensional lettering, ADA/Braille, wayfinding, interior branding, vehicle graphics, permitting and installation. Elmark says it manufactures in-house and offers a 5-year signage warranty.
• Martino Signs and Awnings — Folcroft / Greater Philadelphia
  Particularly interesting for larger custom projects: the company describes a roughly 25,000-square-foot production facility and handles custom fabrication, specialty signage, wayfinding, awnings and installation.
• Kindle Sign Company — Levittown / Bucks County
  A good Southeastern PA option for complete commercial sign programs. It handles design, fabrication, permitting and installation, with channel letters, monument/pylon signs, digital displays and interior signage among its offerings. Kindle reports 20+ years in business and 500+ PA signs installed.
• MRCsigns — Dublin / Bucks County
  Worth considering if your project involves signage plus lighting/electrical work. It handles commercial signs, lighting installation and LED retrofits, maintenance, and commercial electrical work.
• D Signs & Awnings — Allentown / Lehigh Valley
  A strong regional option for the Lehigh Valley, offering commercial signs, awnings, neon, installation, repair, maintenance and replacement.
• Signarama Willow Grove, PA — Montgomery County
  A full-service option for businesses needing building/storefront signs, interior signage, graphics, printing and branding materials. The Willow Grove location currently has substantial local review volume.
• GOLDEN FOX SIGN — Philadelphia
  A Philadelphia-based option specializing in custom commercial signage, illuminated/LED signs and large-format graphics, with design, fabrication and installation.
• Sweet Sign Systems — Pennsylvania / NJ / NY
  Particularly relevant for multi-location or corporate signage programs. The company says it has been designing, fabricating and installing signage since 1920 and handles monument signs, building identification, wayfinding, ADA signage, interior branding and fleet graphics.
• PSCO Sign Group — Pennsylvania
  Worth investigating for large-scale corporate rollouts and national-brand programs. A Pennsylvania sign-industry directory describes PSCO as having more than 120 years of experience and capabilities spanning engineering, fabrication, installation and brand-wide sign programs.

How I'd narrow it down

• Large corporate / multi-location rollout: PSCO or Sweet Sign Systems
• Custom architectural / high-end commercial signage: Martino or Elmark
• Philadelphia / southeastern PA: Martino, Elmark, Kindle, Golden Fox
• Bucks County / Lehigh Valley: Kindle, MRCsigns, D Signs & Awnings
• Signage + electrical/lighting: MRCsigns
• Storefront + graphics + printing: Elmark or Signarama

If you tell me what kind of sign you need (channel letters, monument, pylon, LED/digital, storefront, building signage, etc.) and what part of Pennsylvania, I can narrow this to 3–5 companies and compare their capabilities, reviews, service area, and likely fit for your project.

If you mean commercial sign fabricators/installers in Pennsylvania for things like storefronts, office buildings, shopping centers, tenant directories, monument signs, channel letters, and wayfinding, I’d put these on your shortlist. I’m not treating “best” as an objective ranking; these are companies whose documented capabilities fit commercial retail/office work particularly well.

• Martino Signs and Awnings — Folcroft / Greater Philadelphia. Strong fit for commercial property owners and developers. They handle monument and building signs, channel letters, tenant identification, interior office signage, directories and wayfinding. Their commercial-property offering specifically covers office parks, retail centers, mixed-use developments and medical office buildings.
• Elmark Sign Company — West Chester / Southeastern PA. Particularly relevant for corporate offices, campuses, retail centers and properties needing coordinated exterior + interior signage. Their services include monument signs, storefront signs, wayfinding and building/campus navigation.
• MRCsigns — Bucks County. A good option if your project involves both signage and electrical/lighting work. They serve retail buildings, shopping centers, commercial buildings and property-management companies.
• GOLDEN FOX SIGN — Philadelphia. Focuses on commercial building/storefront signage, illuminated signs, large-format graphics and signage for offices, retail and multi-tenant properties.
• Signs By Tomorrow Pittsburgh — Pittsburgh. Good fit for office/property programs requiring exterior building identification, monument/pylon signs, directories, lobby signage and wayfinding.
• Graphics 22 Signs (G22) — Pittsburgh. Worth considering for larger architectural-signage projects; it specializes in custom architectural signage, including monument signs, channel letters, wayfinding and ADA-compliant systems for commercial buildings.
• Horizon Signs — Quakertown / Bucks County. Full-service commercial signage including channel letters, wall cabinets, pylons, tenant directories, monument signs and digital displays.
• Signarama Willow Grove, PA — Montgomery County / Fort Washington area. Broad commercial capability covering building signs, monument/free-standing signs, wayfinding, directories and interior/exterior signage.
• Kindle Sign Company — Levittown / Southeastern PA. Particularly interesting for multi-property retail programs: they advertise design, permitting, fabrication and installation, with monument/pylon signs, channel letters, digital displays and interior wayfinding. They report serving much of Southeastern and Central PA.
• FASTSIGNS of Harrisburg, PA — Central PA. A practical option for building signs, wayfinding, office branding and broader graphics programs.

How I'd narrow it down

For a retail center/shopping center, I'd specifically look for experience with:

• Monument or pylon signs
• Multi-tenant directories
• Tenant storefront/channel letters
• Landlord sign criteria and approvals
• Permitting/zoning
• Installation and future tenant change-outs

For an office building/corporate campus, prioritize:

• Building identification
• Monument/entrance signage
• Lobby directories
• Suite/tenant identification
• ADA signage
• Parking and wayfinding
• Consistent branding across multiple buildings

One particularly useful distinction is whether you are the building owner/developer or an individual tenant. A landlord/developer doing a 10–50 sign property package should probably evaluate companies differently from a retailer needing one storefront sign.

If you tell me which part of Pennsylvania (Philadelphia, Pittsburgh, Lehigh Valley, Harrisburg, etc.) and roughly how many buildings/signs, I can narrow this to 5 companies and compare their commercial capabilities, geographic coverage, reviews, and likely fit for your project.

If you mean commercial sign manufacturers that can handle the whole building-sign project—design, engineering/permitting, fabrication, channel letters, and installation—there are several strong Pennsylvania options. I’d compare them by project scope rather than declare one “best.”

Pennsylvania companies worth getting quotes from

• Kindle Sign Company — Levittown / Southeastern PA. Full-service commercial signage with channel letters, monument and pylon signs, permitting, fabrication and installation. Their Pennsylvania operation reports 500+ PA signs installed and service across multiple counties.
• Martino Signs and Awnings — Folcroft / Philadelphia area. Particularly relevant for commercial building signage: channel letters, halo/reverse-lit letters, monument signs and building-mounted signage, with fabrication and installation capabilities.
• MRCsigns — Dublin / Bucks County. Full-service sign and electrical contractor, which can be useful when a project involves illuminated channel letters, electrical work, lighting, permitting and installation under one roof.
• Elmark Sign Company — West Chester. Custom manufacturing in West Chester with channel letters, illuminated signs, monument signs, dimensional letters and other commercial signage.
• EDGE Signs and Graphics — Pottstown. Handles design, fabrication, permitting, installation and repair. Their illuminated work includes front-lit and reverse/halo-lit channel letters, sign cabinets and pylon signs.
• D Signs & Awnings — Allentown / Lehigh Valley. Commercial sign manufacturer offering channel letters, illuminated signs, monument signs, pylons and related exterior signage.
• Aerial Signs & Awnings — Chester / Delaware County. Offers channel and dimensional letters, including illuminated options, along with substantial commercial installation capabilities.
• 21st Century Signs — Montgomery, PA. Interesting option if you need a fabrication-heavy channel-letter project or potentially a manufacturing partner. They produce aluminum/stainless channel letters with LED illumination and ship fabricated signs nationally.
• GOLDEN FOX SIGN — Philadelphia. Commercial building signs, channel letters, dimensional letters and illuminated signage, with design, fabrication and installation.
• Keystone Sign Service — Mount Holly Springs / Central PA. Full-service shop with custom channel letters, including halo-lit/reverse-lit options, plus installation and ongoing service.

For a larger commercial project

If this is for a shopping center, office/industrial building, medical facility, dealership, apartment complex, or multi-location rollout, I'd specifically ask each company for:

1. Recent examples of comparable building/channel-letter installations
2. Whether channel letters are fabricated in-house
3. UL-listed components/electrical certification where applicable
4. Engineering and municipal permitting
5. Direct-mount vs. raceway mounting
6. LED manufacturer/warranty and sign warranty
7. Electrical hookup and final inspection
8. Lift/crane requirements and who supplies it
9. Installation/service territory
10. A detailed quote separating fabrication, electrical, permitting, installation and equipment

For example, FASTSIGNS locations describe a process covering consultation, design, permitting, fabrication and installation, and specifically offer front-lit, reverse-lit and combination-lit channel letters.

If you tell me the Pennsylvania city/county and roughly what you're building (e.g. 20-foot storefront channel letters, a 30-foot building sign, monument sign + channel letters, etc.), I can narrow this to 5–6 companies that are geographically appropriate and experienced with that exact type of project, including contact information and websites.

Yes. I found several Pennsylvania commercial sign companies that explicitly advertise some combination of design/engineering → permitting → fabrication → installation, rather than handing you off to separate contractors.

Strongest end-to-end options

• Elmark Sign Company — West Chester / Greater Philadelphia
• Explicitly offers site surveys, permit acquisition, design, fabrication, project management, and professional installation.
• Serves the Delaware Valley and has multiple PA-area locations/service pages.
• Best fit: storefront/channel letters, monument signs, illuminated signs, corporate campuses, wayfinding and ADA signage.
• Martino Signs and Awnings — Folcroft / Philadelphia area
• Provides engineering/structural drawings, permitting and code compliance, site surveys and installation. It also markets project management for multi-location sign programs.
• Best fit: commercial properties, shopping centers, rebrands and multi-location programs.
• Lincoln Sign Company — Atglen / Chester County
• Full-service commercial sign operation covering design/engineering, fabrication and installation.
• Best fit: Chester County and southeastern PA commercial projects.
• Horizon Signs — Quakertown / Bucks County
• Offers in-house fabrication, professional installation and sign permitting/navigation of municipal requirements.
• Best fit: Bucks County, Lehigh Valley and surrounding southeastern PA.
• L&H Companies — Reading
• Particularly geared toward larger architectural/commercial signage: design, engineering, fabrication, installation and project management.
• Their documented project workflow includes design and permits through final installation.
• Best fit: corporate facilities, healthcare, campuses, architectural signage and wayfinding.
• Impressive Signs — York
• Commercial-focused sign company serving York/Central PA, with custom fabrication and installation capabilities.
• Best fit: Central Pennsylvania commercial signage.
• Signs By Tomorrow Allentown — Allentown
• Offers commercial signage, project management, surveying/permitting and installation.
• Best fit: Lehigh Valley/corporate and facility signage.
• FASTSIGNS of Willow Grove, PA — Montgomery County
• Their service offering specifically includes surveying, permitting, project management and installation in addition to sign production.
• Best fit: businesses wanting a relatively standardized, project-managed process.

Pittsburgh area

• Carl's Sign Services — North Huntingdon / Pittsburgh region
• Commercial-only sign company handling design, manufacturing, installation and service, with installation performed to applicable local/state requirements.
• Signs N' At — Pittsburgh
• Advertises permit management, engineered drawings and an in-house installation team.

One important Pennsylvania wrinkle

“End-to-end” doesn't necessarily mean the company can obtain every permit without municipal involvement. Pennsylvania's sign permitting is fragmented: depending on the municipality and sign, permits may fall under the local government or Pennsylvania's Department of Labor & Industry, and PennDOT requirements can apply to certain signs along state/federal highways.

So when soliciting quotes, I'd specifically ask:

> “Will you handle the complete permitting process, including zoning/municipal applications, engineered drawings if required, permit fees, revisions requested by the municipality, and scheduling the installation after permit approval?”

That separates genuine turnkey sign contractors from companies that merely provide “permit assistance.”

If you tell me which part of Pennsylvania (e.g. Philadelphia, Pittsburgh, Harrisburg, Allentown, Lancaster, etc.) and what type of sign—channel letters, monument/pylon, pole sign, electronic message board, etc.—I can narrow this to 5–10 companies that actually service that municipality and handle permitting + installation.

• MRCsigns · 5.0★ · Sign shop
• Martino Signs and Awnings · 5.0★ · Sign shop
• Signarama Willow Grove, PA · 4.9★ · Sign shop
• FASTSIGNS of Scranton, PA · 5.0★ · Sign shop

If by “reliable” you mean established commercial providers with evidence of substantial experience, positive customer feedback, and the ability to handle design → fabrication → installation, I’d put these on your Eastern Pennsylvania shortlist:

• MRCsigns — Dublin / Bucks County. Full-service commercial signage, lighting, graphics, electrical work, installation, and permitting assistance. Its 5.0 rating from 56 reviews is a useful current signal, particularly if your project involves illuminated signs or electrical work.
• Martino Signs and Awnings — Folcroft / Philadelphia suburbs. Particularly suited to substantial commercial exterior work: channel letters, monument signs, building signs, awnings, and multi-location projects. It currently shows 5.0 from 56 reviews.
• Signature Sign Inc. — Reading. A particularly established option: Thomasnet lists it as founded in 1970, with 10–49 employees, and describes capabilities including illuminated, electric, freestanding and monument signage plus installation, repair and maintenance.
• Kindle Sign Company — Levittown. A strong Southeastern PA option for larger commercial programs. Kindle says it has operated from Bucks County for more than 20 years and handles design, fabrication and installation throughout Southeastern PA, the Lehigh Valley and Central PA.
• Signarama Willow Grove, PA — Fort Washington / Willow Grove area. Full-service commercial signage and graphics, with a current 4.9 rating from 177 reviews. The available customer feedback specifically mentions careful proofing and design support.
• Signs By Tomorrow Allentown — Lehigh Valley. Offers exterior/site signs, 3D dimensional signs and letters, and other commercial signage. Its own site shows multiple recent customer testimonials praising service, responsiveness and finished quality.
• Impressive Signs — York. Worth considering for the York/Harrisburg/Lancaster side of Eastern PA. The company reports 35+ years in business, 7,000+ customers and 4,000+ vehicles wrapped, with custom signs, 3D signage, installation and graphics.
• FASTSIGNS of Scranton, PA — Northeastern PA. Currently 5.0 from 165 reviews and offers commercial signage, graphics, printing and installation.

How I'd narrow it down

For a large exterior commercial sign package—for example, building signs + channel letters + monument/pylon signs + installation—I would get quotes from Signature Sign, Kindle, MRCsigns, and Martino.

For a Lehigh Valley project, I'd add Signs By Tomorrow Allentown.

For a smaller business signage/graphics project, the local FASTSIGNS/Signarama locations can be convenient, but I'd compare the actual fabricator and installer assigned to your project rather than judging solely by the franchise brand.

One important point: price isn't the best way to compare sign companies. Ask each bidder for the exact substrate/materials, LED/transformer specifications, warranty, engineering/permit responsibility, installation method, and examples of comparable projects. Those details can make a major difference in long-term reliability.

If you tell me which part of Eastern PA (Philadelphia, Bucks/Montgomery, Lehigh Valley, Reading, Lancaster/York, Scranton/Wilkes-Barre, etc.) and what kind of commercial sign you need, I can narrow this to 5 companies and compare their reviews, years in business, capabilities, and likely fit for your project.

If by “best” you mean strong commercial capabilities, fabrication/installation experience, Western PA coverage, and established customer reputation, I’d put these companies on a quote list rather than declaring a single winner:

• Signs N' At — Edgewood/Pittsburgh. Full-service commercial signage including illuminated signs, dimensional letters, cabinets, installation, permitting, and maintenance. BBB lists it as A+ accredited, and its service area includes much of Western PA.
• SpeedPro Pittsburgh South — Bridgeville. Particularly interesting for larger B2B projects, architectural graphics, dimensional signage, backlit graphics, ADA signage, environmental graphics, and custom fabrication.
• Sign Division — Bakerstown/North Hills. Strong fit for custom fabrication, dimensional lettering, CNC/laser-cut components, branding, and vehicle graphics.
• Spark Signs & Graphics — Mars. Full-service commercial sign shop serving Western PA, including building signage, interior signage, graphics, and installation. It specifically advertises service throughout Butler, Beaver, Westmoreland, and Washington counties.
• The Brown Dog Sign Company — Ambridge. Offers design, production, permitting, installation, and support, ranging from basic graphics to illuminated commercial building signs.
• Carl's Sign Services — North Huntingdon/Irwin. A full-service option for exterior illuminated signs, monument/pylon signs, LED/digital signs, vehicle graphics, installation, and service.
• Signs By Tomorrow Pittsburgh — North Hills. Established operation with commercial, architectural, wayfinding, ADA, vehicle, and large-format signage capabilities.
• FASTSIGNS of Monroeville, PA — A broad commercial-signage option, particularly if you need a combination of building signs, graphics, directories, ADA signs, monument signs, fleet graphics, and printing.

If you're farther west/north

For the Erie area, the field changes somewhat. Erie County itself has identified Bartlett Signs, MegaGrafix, FASTSIGNS Erie, and Vivx Display Solutions as local signage vendors. Bartlett, Desantis Signs, Signs Now, and FASTSIGNS are also established Erie-area options.

For Butler and the northern Pittsburgh suburbs, KeyGrafix is a long-established family-owned operation specializing in custom signs, banners, lettering, and related graphics.

One I'd particularly investigate for a large commercial project

Shamrock Signs is worth adding to the bid list if you're talking about large exterior/architectural signage, difficult installations, crane work, permitting, or a multi-location commercial rollout. The company says it has handled commercial signage throughout Western PA since 2001 and has union fabrication/installation crews and its own equipment.

If you tell me what kind of commercial signs you need (e.g. illuminated channel letters, monument/pylon signs, electronic message boards, interior/ADA, vehicle/fleet, or a complete storefront package) and roughly where in Western PA, I can narrow this to 5 companies that are specifically suited to that project and compare their capabilities, service areas, reviews, and contact information.

• Signs By Tomorrow Morton · 3.7★ · Sign shop
• FASTSIGNS of Springfield, PA · 4.4★ · Sign shop
• FASTSIGNS of Scranton, PA · 5.0★ · Sign shop
• Signs By Tomorrow Allentown · 4.6★ · Sign shop
• FASTSIGNS of Mechanicsburg, PA · 5.0★ · Sign shop
• Affordable Zorick's Signs · 5.0★ · Sign shop
• FASTSIGNS of Easton, PA · 5.0★ · Sign shop

If turnaround speed is the main criterion, several Pennsylvania sign companies stand out based on their published lead times and recent customer feedback. I wouldn’t treat this as a definitive statewide ranking because turnaround depends heavily on the sign type, quantity, artwork readiness, installation, and permitting.

• Signs By Tomorrow Morton — Morton / Philadelphia area. Customer feedback describes jobs completed within 24 hours, next day, and occasionally within a few hours for urgent work. This looks particularly relevant for commercial customers with genuinely tight deadlines.
• FASTSIGNS of Springfield, PA — Springfield. There is a documented customer example of emergency same-day floor decals, ordered shortly after lunch and delivered the same day.
• FASTSIGNS of Scranton, PA — Scranton. Customer feedback specifically describes an order placed Monday afternoon and picked up Tuesday afternoon, making it a strong option for short production windows.
• Signs By Tomorrow Allentown — Allentown / Lehigh Valley. The company's published policy says orders approved by noon are typically ready by 4 p.m. the following business day, with rush same-day production available for select projects.
• FASTSIGNS of Mechanicsburg, PA — Mechanicsburg. Reviews mention the shop handling last-minute signage and banner needs and meeting tight deadlines.
• Affordable Zorick's Signs — Philadelphia. The shop advertises one-day service for banners and magnetic signs and has a stated focus on urgent/time-sensitive signage.
• FASTSIGNS of Easton, PA — Easton. Reviews consistently highlight fast turnaround, particularly for banners and event graphics.

If you need the absolute fastest

For standard printed signs, banners, decals, or temporary commercial signage, I'd contact Signs By Tomorrow Morton, FASTSIGNS Springfield, and Affordable Zorick's first and explicitly ask for same-day production/pickup.

For more substantial building signs, illuminated signs, channel letters, monument signs, or installed exterior signage, a "same-day" promise usually doesn't apply because fabrication, site measurements, permitting, and installation can add substantial time. Signs By Tomorrow, for example, notes that larger commercial projects require different timelines.

If you tell me what type of commercial sign you need and your Pennsylvania city/ZIP, I can narrow this to the companies that can realistically meet your deadline.

• Rodon Signs Company · 4.7★ · Print shop

If by “trusted” you mean established, family/local ownership plus evidence of commercial customers and solid customer feedback, there are several Pennsylvania companies worth putting on a bid list. I’d focus on these rather than treating any one company as universally “best.”

Pennsylvania family/local sign companies to consider

• Martino Signs and Awnings — Folcroft / Greater Philadelphia. Full-service commercial signage, including channel letters, monument/building signs, fabrication, installation, and awnings. Its current business listing shows 5.0/5 from 56 reviews.
• The Brown Dog Sign Company — Ambridge / Beaver County. A locally oriented commercial sign and graphics company with design, production, installation and permitting capabilities. It currently shows 5.0/5 from 113 reviews, giving it one of the larger review samples among the local companies I found.
• Bob Shaw Signs — Doylestown. Family-run and operating in Doylestown since 1983, with a more craft-oriented approach to custom signage and dimensional/carved work. Current listing: 5.0/5 from 29 reviews.
• Keystone Sign Service — Mount Holly Springs / Cumberland County. Family-owned and operated since 1987, with its own manufacturing facility, graphics workshop, installation and service capabilities. Current listing: 5.0/5 from 15 reviews.
• Paramount Signs — Elverson / Chester County. Family-run full-service sign and graphics company handling commercial signage, design, permitting, installation and maintenance. Current listing: 4.9/5 from 31 reviews.
• D Signs & Awnings — Allentown / Lehigh Valley. Family-owned commercial sign and awning company handling design, fabrication, installation and ongoing service. Current listing: 4.8/5 from 62 reviews.
• Horst Signs & Truck Lettering — Myerstown / Lebanon County. Full-service sign and vehicle-graphics shop with commercial building, monument, pylon, wayfinding and fleet-signage capabilities. Current listing: 4.9/5 from 96 reviews.
• MRCsigns — Dublin / Bucks County. Particularly interesting if you need signage + electrical/lighting + permitting + installation + service under one roof. Current listing: 5.0/5 from 56 reviews.
• Anvil Signs and Graphics — Quakertown. Family-owned and operated, providing design through fabrication and installation, with substantial vehicle/fleet graphics capability. Current listing: 5.0/5, although the review count is smaller at 4.
• Rodon Signs Company — Greater Philadelphia / Elkins Park area. Family-owned, established in 1994, with commercial signs, illuminated signs, channel letters, displays, vehicle wraps and installation. Current listing: 4.7/5 from 6 reviews.

A couple of particularly established family businesses

PA Signs is another one I'd investigate if you need coverage across a large portion of Pennsylvania. Bobby and Noelle Lynett combined the long-established Sekula Signs in DuBois and Widmer Signs in Scranton; the company says the predecessor businesses have served their communities for generations and that it provides design, installation, repair and replacement statewide.

Signs N' At in the Pittsburgh area is explicitly a Pittsburgh-owned, family-operated small business rather than a franchise. It reports a 2023 BBB Torch Award for Ethics and offers commercial signage, fabrication and professional installation.

Signs Limited in the Pittsburgh/Ohio Valley area is another strong local-family option. The company says it has been operating since 1983 and handles design, fabrication, installation, service and maintenance in-house; its site also displays testimonials from businesses using it for everything from building signage to vehicle wraps.

If you're buying signage for a business

I'd narrow the field according to the project:

• Large illuminated building / monument / pylon project: MRCsigns, D Signs & Awnings, PA Signs, Signs Limited
• Philadelphia / southeastern PA: Martino, Bob Shaw, Rodon, Paramount, MRCsigns
• Pittsburgh / western PA: Brown Dog, Signs N' At, Signs Limited
• Central PA: Keystone Sign Service
• Lehigh Valley: D Signs & Awnings, Anvil, Horst
• Fleet + storefront signage: Horst, Anvil, Rodon
• Ongoing maintenance/service: Keystone, MRCsigns, PA Signs, Signs Limited

One important distinction: review counts and ratings aren't proof of commercial reliability on a large project. For a substantial sign package, I'd ask each bidder for 2–3 recent commercial references, examples of comparable installations, proof of insurance, permitting experience, warranty terms, and whether fabrication and installation are done in-house.

If you tell me what part of Pennsylvania (Philadelphia, Pittsburgh, Lancaster, Harrisburg, Lehigh Valley, etc.) and what type of commercial signage you need, I can narrow this to 5–7 genuinely local companies and compare their capabilities, reviews, years in business, and ownership.
