Hmmm...correct me if I'm wrong but I think the problem was how to manage a larger team, not neccesarily how to form a larger one. My advice would simply be taking cues from the team organization threads. It seems that with hierarchies, more jobs are created yet people are still held accountable when there's good leadership. Of course it could fail but it's all about how much effort everyone puts into it.

After a quick search, this thread was helpful: Team Hierarchy

On that thread, I made a post that had even more links to other threads that I found helpful...yay for links within links.
