How to monetize? My tool has helped 10,000 people but only made £1

I built a tool that helps people appeal parking fines in the UK. Nearly 10, 000 people have used it so far-but I don’t have a single paying customer.
I've just turned on ads and only made £1 so far not a lot - but I'm happy a built a tool to help people fight their unfair fines without the headache.
The idea came after I got hit with a £195 private parking fine for no good reason. I spent hours researching how to appeal it and realised the system is intentionally confusing. Most people just pay up because the process is designed to wear them down.
