Replying to Question about sponsors

HI my friend is trying to get sponsored for anything so his mom will let him keep skiing.  I was wondering how good you have to be?  I will list what he can do on the bottom.  As well if you have the power to sponsor him that would be great.  We are making an edit soon, we just need a few more clips.
Trick list
Backflips
spins up to 900
spins up to 540 switch
corks
270 on and off rails
switch ups on rails
He can also do  grabs with all of these tricks where they would fit in. 

And please don't troll he is only 15 and needs a sponsor because his parents are making him get a job and he wont have time to ski.
