You have a method, and clients get results from it. The only way to get paid for it is to be in the room, which means your income stops when your calendar is full.
What changes that is packaging what you already teach: a guide, a workbook, a course, a set of templates, a recorded workshop or a tool that people can buy while you work on something else.
That needs somewhere to sell from. Most people pick a platform that takes a cut of every sale, or build on WordPress and end up maintaining a pile of plugins. Djangify Self-Hosted is a third option: a complete shop that you own outright.
