I've always wanted to make a video game. I have a lot of good ideas, I think. But I don't think there's a job out there where you can pretty much just tell a group of people what to make and they'll do it. Unless you run the company.
There is something *similar*, called rent-a-coder, it is for computer and programming based needs but does have a game development section.
I however would very much be interested in your idea, at least to hear it. PM it if you want or post it here, it's all the same to me.
oh and shameless plug time?
