The Koerner Office: How Sandwich Boards Can Hit $10K+/Mo

A free restaurant sandwich board can become a high-margin business—and the real money comes from the upsell. In this condensed version of The Koerner Office, host Chris Koerner breaks down a surprisingly simple ad model built around local business advertising, restaurant foot traffic, and repeat visibility. What starts as a $350 print job can generate thousands in recurring revenue, with Rachel explaining how the team sells six ad spots per board, uses Canva, ChatGPT, and Stripe, and turns each placement into a lead source for websites, reputation management, and AI services. This quick listen trims the full episode down to a few minutes while still covering pricing, prospecting, referral generation, and why high-traffic locations matter. If you’re interested in business model innovation, startup ideas, and low-cost marketing, you’ll walk away with a clear picture of how one simple physical product can open the door to a much bigger agency offer.
