All or Nothing: My coding agency only takes payment if the client is 100% happy

Hey IH!
I am testing out a new coding agency idea. I call it https://quickly.codes.

My goal is to help Indie Makers develop fast, affordable SaaS and Web Apps quickly.

I'm launching on ProductHunt this Thursday, and I would love your support and feedback!

What do you think about this business plan, and how should I improve it. How can I get my first customer?
