Local tradesClaude + Codex (AI phone agent on ChatGPT voice)

Run a mobile repair business on a pricing spread, with AI checking your ads and errors every morning

Result

self-reported

About $200K in revenue and 178 orders, from a non-coder who took a $25 Claude course and built the site in six weeks.

Brandon Theriot turned one bookmarked playbook into Mobile Diesel Repair in Phoenix. Mechanics set their own rate (about $125/hr), he adds 30%, and scheduled Codex jobs check his ads, analytics and site errors every day. He told the whole story on The Practical AI Show, Ep 59.

Try it now

  1. Pick one boring local service you understand and work out the spread: what the skilled pro charges (Brandon: about $125/hr), your markup (30%), and what the customer pays (about $175). You bring the leads and the billing.
  2. Build a site with one in-depth page per service and one page per area you cover. Brandon used Claude (Opus); it took six weeks and about four versions that broke before one worked.
  3. Set up a scheduled AI job that checks ad spend, conversions, traffic and site errors every morning and emails you a summary.
  4. Keep a human on intake calls until your AI phone agent catches up. Brandon’s agent completes 15–20% of intakes; his partner gets about 60%.

What to watch out for

Self-reported by Brandon on the show. The AI phone agent still trails a human (15–20% vs about 60% full intakes), so don’t hand it your phones yet. With no physical shop there’s no Maps listing, so he ranks with service and location pages. Build it with Page: one page per service and one per area, on a site you own.
