There are lots of ways to get recognized as a pro skier and have companies start wanting to pay you in return for the advertising your skiing provides. From my experience there are 2 real ways to get into the scene. The Fast and well paying route is via competitions. Learn the tricks then put them down in a run in the biggest open competition you can find or if you can get into comps that aren't open events even better. Results are fast tracks because they are hard evidence to companies that 1 judges have said you are good at skiing and 2 that you are going to get some sort of coverage from your results. The other main route that is usually takes longer though also lasts longer and is more fun imo is the filming route.
there is no set path taking this route but it is well established. Similarly to finding the biggest open comps with competing to get recognized, you do the same with filming trying to find the best recieved film crew or people to start filming with. Anything from small companies to people who are known for putting out baller edits. Even putting out ur own edits can help if its ur only option and ur good enough.
in either case whether competing or filming you start with small edits/companies or competitions and as you prove urself you get invited to the bigger comps or to film with the bigger companies. As you work your way up these ladders sponsors begin to notice and want you though in the ski industry it's never a sure fire thing. Salaries and paychecks are extremely inconsistent in the sport as the adverrtising and ability of different skiers is extremely subjective as is judging. One persons "best skier" is another persons aerialist while another's "best skier" is a lethargic pot head. sorry this is long, i've been bored and stuck on the island of morel
