Lol, well everybody has ideas, that's the easy part... Basically it sounds like you've got a game idea and want others to make it for you. Am I uhm about right?

No offense, but you should really show something of what you've made or done so far as designer. Just having an idea is not enough.

Also, if your ideas are truly yours and original, then ultimately you will have a copyright over it. Making sure not to spill to much of the details of your idea is usually a good idea, but you can't work with people and not say what your intentions are,

Cheers
