In this interview, Chris Koerner talks with Rachel, co‑founder of a local advertising side‑hustle that places dry‑erase sandwich/sidewalk boards in high‑foot‑traffic venues such as restaurants, auto shops, and even a Humane Society location. Rachel walks through the entire business model: each board holds six ad slots sold at $600 per slot per year ($3,600 per board) with a cost of $350‑$400, yielding 85‑90% margins. She explains how they acquire customers—starting with cold DMs and emails, achieving a 10‑30% response rate, and then closing 1‑2 boards per outreach batch by leveraging referrals, which she calls the “secret sauce.” The conversation covers ad creation (Canva, ChatGPT, Claude), the tech stack (Stripe for payments, GoHighLevel for CRM, Instagram/Facebook/YouTube for outreach), platform‑specific messaging limits, and the importance of targeting niche locations (restaurants, auto shops, pet‑related businesses). Rachel shares market sizing insights (roughly one restaurant per 200 people in the U.S.) and highlights the scalability of the model, envisioning boards in every restaurant worldwide. She emphasizes the side‑hustle’s earning potential (around $3,000 / month) and encourages entrepreneurs to think beyond the boards, offering agency services like website builds and AI automation. The interview ends with links to the Community Cash Playbook YouTube channel and their agency site, Big Sky Automation Services.
