I think you need to expand more on this.

What do you offer for the team and what positions are you looking for.

Some additional information like a brief description of your past completed games or projects would aid in attracting people.

I don't want to sound crude, but the way you are asking this question tells me that you aren't very experienced in this area. It's OK, I'm not a professional either. But aside the fact that your question is just too vague, it shows that you don't understand the complexity of such a game.

Even if someone is interested in working with you, do you have expertise to offer? Programming? Art? Design experience? Simply having an idea isn't going to get you anywhere; everyone has their own ideas.
