I really hope the kid with the 360 iron cross was kidding.
I don't think I'd even try to get sponsored unless plenty of switch, unnatty, inverts, rail tricks(presses, spins, switchups) were in my bag. When you are in control enough to do all 4 720's with style and with solid grabs or rotation patterns(corks, etc) then you can probably start thinking about actively trying to get sponsored.
until then, get to be friends with the important guys, throw DOWN in front of them, and eventually you'll get there  if you are dedicated enough.
