Even if you can't perfectly execute on your idea, the fact that you've built something yourself probably means that a) you care enough about the idea that you want to see it built one way or another, and b) you've thought through how the product will work sufficiently to build something. I would guess that most people who come to developers with ideas haven't actually thought the product though very much.

If you make a prototype that shows promise and show it to me, I'm more likely to start thinking "this is really cool, how can I make this awesome?" than "this person wants me to build something for them for free".
