People post the apps they want on a public board every week.
Cold outreach is the worst part of selling. You interrupt people who never asked, and most of them never answer.
The requests board is the other way round. People post the app they want, with their need, budget and timeline. A Studio takes a request up, the requester accepts, and Deployr quotes a fixed price and builds it. The order carries your Studio's code.
You do the part you are good at: understanding what they need, and seeing it through.
