Where can I find fellow developers who are looking for help to create a startup?

Are there any collaboration websites whereby people pitch ideas and a group of people 'join' the project in an effort to create some kind of prototype?

Edit: @Vitor Braga - Seriously i'm not looking to make money, just finding developers who are interested in making a trivial little app with someone else.

Edit: It may be worthy to explain that I live in a remote area of Australia.
