Since alot of ppl want to know the thing from rex i wil just post it
Hey Drew what's up?
the best way to go about it for you would be to start with either a local ski shop, or a local rep for a company. You need to make it professional so you make a resume just like you would for a job only it's for skiing, it should include Goals, past achievements, results, and some other stuff about you, if you can include pictures that will definitely help and even more than pictures if you can compile a short video of yourself to show what you can do that's the best. with each resume you send to a shop or a company send a cover letter just like you would on a resume, make it personalized to the company or the shop or the rep so on, it should basically be stating why you want them to sponsor you (pump up their brand say how many great things you've heard about them, even if it's not totally true) then tell them what you can do for them, ie. Exposure, being a good spokesperson and what not, and why by them sponsoring you would be beneficial to them.
hope this helps get you started
