running an adword campaign cost money, not everyone has money these days :X
What I mentioned has nothing to do with adwords. The partner manager scheme is free 1 on 1 consulting and advice from a Google employee to take YT channels (with potential and already growing) to the next level. Do a search for Youtube partner managers and consultations. That's what you should be aiming for.
