Fly-boy, change that handle first.
It's important to start early if you want a good chance with the majors. Yes, there is more to life than QF. The 'age commensurate with experience' thing becomes a factor as you get older.
I wouldn't be handing over that much money with one outfit. Hold onto it and pay bit by bit, keep them hungry. You may also want to change schools at some stage. It's not easy when you've paid up front.
Good Luck.
