About Highway Poster Service

I run Highway Poster Service, an independent creative studio producing memorable billboard designs for local businesses.

Why work with one person

Highway Poster Service is just me. I don't have agency overhead.

Working directly with me means two things for you:

• You talk to the person designing the graphics and writing the copy for your billboard.
• You receive three completed concepts in five business days for a flat $1,500 fee.

Billboard companies make money leasing space, not making good ads. Their free design work gives them no reason to care if your board actually works. I research what sets you apart and build the one message drivers will remember.

Who I work with

I design billboard ads for local businesses that rely on strong name recognition:

• Attorneys and legal practices
• Medical clinics and urgent care centers
• Contractors, plumbers, and HVAC trade fleets
• Independent restaurants and fast food spots
• Community banks and real estate firms

Businesses I do not serve

I do not take projects that fail outdoor visibility standards or contradict my format rules:

• Political campaigns and candidate advocacy
• Retail promotions requiring price lists, inventory grids, or coupons
• Speculative pitches, unpaid contests, or classified ads
• Any billboard requiring phone numbers, URLs, or fine print

Markets served

I work remotely with clients across the United States. Work is concentrated in high-traffic metro corridors:

• Austin, Birmingham, Charlotte, Cleveland, and Harrisburg
• Indianapolis, Jacksonville, Kansas City, and Knoxville
• Milwaukee, Nashville, Pittsburgh, Salt Lake City, San Antonio, and St. Louis

I accept billboard projects in other US media markets if the structure fits standard outdoor vendor specifications.

Pricing and deliverables

$1,500 flat fee covers three distinct billboard concepts. Finished files arrive in five business days.

You receive production files built to vendor specifications:

• Print-ready vector artwork for Lamar, Outfront, and Clear Channel displays
• Pixel-exact files for digital LED boards
