Turn what you can build into something you can sell. Define a clear offer, a scope, and a price.
A service is a clear promise: "I will build X, that does Y, delivered in Z days."
Vague: "I do AI stuff." Clear: "I build a support chatbot trained on your FAQ, live in 5 days, for $800."
The clearer the promise, the easier it is to sell and to deliver. Pick one thing you can do well and package it.
