Team Requests are only allowed in special circumstances and tend to require that you're able to have something to show for it. The majority of team requests get locked.
But Zotoaster gave some useful advice. If you do have something valuable to offer then people are more likely to team up with you or conversely, have you on their team.
But question, why is college a bad idea? Whilst I don't think it's a necessity for getting a good job, but I know some degrees out there are pretty damn useful for this kind of work. Obvious you don't want to be told that, but I figure I'd offer the reason behind my question.
Also, what kind of thing are you looking to do with your team of people? What can you offer them? Can you provide them with confidence that your team will reach these goals? Have you got something to show? After all, people will want to know they're teaming up with the right people for the job.
You believing in yourself or you really wanting something badly might not be enough to convince somebody, at least anybody who'll be useful to you.
