Ideas are cheap. Ask ChatGPT and it will give you dozens. Heck, ask almost any random person, and they will have business ideas. What's hard is (a) finding a good idea, (b) investing the time and effort to make it reality, and finally (c) marketing it successfully.
How to build it, the labor, the design, the marketing and the capital? Thats where you come in!
