In this episode Chris Koerner interviews Rachel, co‑founder of a niche advertising business that places aluminum dry‑erase sandwich boards in high‑traffic local venues (restaurants, coffee shops, gyms, auto shops, and community spaces). The boards are provided to the host venue for free, while local businesses purchase ad slots at $600 per spot per year (six slots per board, $3,600 total). Production costs are about $350‑$400 per board, yielding ~85‑90% profit margins. Rachel explains how they source boards from a local Missoula printer, design ads using Canva or AI tools like ChatGPT (and occasionally Claude), and acquire host locations via Instagram DMs, in‑person visits, and referrals from owners. They leverage owner referrals heavily to fill ad slots quickly, achieving a near‑100% close rate when appointments are set. Advertisers are sold the board placement upfront, and the relationship is then leveraged to upsell digital services—website builds, reputation management, AI chat/receptionist tools—delivered by Rachel’s husband. The business uses Stripe for payments, GoHighLevel (GHL) for CRM, and promotes services on Instagram, Facebook, and YouTube. They have experimented with niche partnerships, such as boards in auto shops and a Humane Society location targeting pet‑related businesses, demonstrating flexible market segmentation. The conversation also covers pricing variations, contract terms, scalability challenges (non‑recurring board sales, need for continual new host locations), and the importance of trust and micro‑commitments in selling higher‑ticket digital services. They have generated roughly $50,000 in board revenue in six months, with $45,000 profit, and are on track for $10‑$15K monthly revenue (≈85% profit). They have about 63 unique advertisers, half of whom have been upsold to additional services. Rachel shares practical tips on DM response limits on Facebook vs. Instagram, remote closing ideas (FaceTime pitches), and future visions of widespread sandwich board advertising.

The episode ends with gratitude and encouragement for listeners to consider this low‑tech, high‑margin side hustle.
