I built a website as a bit of a technical exercise, but I think it could actually turn into a business. Do I need a business coach?

I'm a developer currently working in AWS/Node/Postgres. About 20 years experience. I built this app that can be used to help people save money on their streaming service bills. I think it can turn into a little bit of cash on the side if I built it up.

There are sites that do the same thing but I have never heard of them and I bet you haven't either. And they charge a silly amount, like $8 a month, for something that is designed to save money.

I reached out to a friend who used a business coach to get her consulting business off the ground. She referred me to a coach who then referred me to a different coach (because the first coach only works with women). We chatted back and forth for a bit. She told me that she didn't think that she could help me because she didn't understand that problem space etc so she was going to refer me to somebody else. That was about 4 weeks ago. I sent a 👋 a week later and got no response. So I'm writing that person off.

I don't know how to launch a business. I've got plenty of things to do in my life and learning marketing is just not something I'm interested in. I just know how to code. Should I hire a business coach? And how would I go about finding one?
