I built a fully automated website-selling machine for UK tradespeople. Here's exactly how it works.

Six weeks ago I had an idea: tradespeople in the UK are notoriously bad at having websites. Plumbers, tilers, electricians - great at the trade, invisible online. Meanwhile they're losing jobs to competitors who show up on Google.

So I built a system to fix that automatically.

Here's what it does end to end, with zero human involvement:

🔍 Step 1 - Lead discovery.

A scraper hits Google Maps and pulls tradespeople across 40+ UK cities: plumbers, electricians, plasterers, roofers, tilers. Filters out anyone who already has a website. Scores each lead by rating, review count and trade category.

🤖 Step 2 - AI site generation

Claude (Anthropic's model) writes bespoke copy for each business — unique tagline, services, about section, colour palette. No templates. Each site feels built for that specific business.

🚀 Step 3 - Automatic deployment

The site deploys to Netlify on a custom subdomain: businessname.preview.[MY DOMAIN].co.uk. A screenshot is taken automatically for WhatsApp previews.

📱 Step 4 - Outreach

The lead gets a WhatsApp message with their site screenshot attached: "I built [Business] a website. No website = lost jobs. £299 one-off. YES or STOP."

🧠 Step 5 - Intent classification

Replies are classified automatically: positive, negative, unknown. Positive triggers a preview link send. Payment link goes out. Day 3 and Day 7 follow-up sequences run automatically.

📞 Step 6 - Call list

A dashboard surfaces warm leads for manual follow-up, sorted by temperature: payment link sent → said YES → preview viewed.

The whole stack: Python, FastAPI, SQLite + GCS, Cloud Run, Twilio, Netlify, Anthropic API, Stripe.

8,500+ messages sent. Running 24/7 on £5/month infrastructure.

I'll post the real numbers and what I'd do differently next.
