Well firstly, you should know that ideas are worthless, particularly if you don't have the necessary skills and/or funds to make them a reality.

Everybody has ideas, so you'll need to set yourself apart if you want to create a team. Also, nobody wants to make someone else's dream come true,

so unless you're planning on paying the developers, marketers, testers etc, then good luck.

Otherwise, if you've got the cash, time and dedication to make this happen, start posting job advertisements in the services section, you'll surely be able to get some basic help for free, but anything substantial you'll almost certainly have to pay for, unless you happen to be besties with just the right people.
