Replying to Switch from snowboarding to skiing?

I've been snowboarding for four years now and am thinking of switching to skiing. I'm 15 and can do back flips and up to 540s regular. I'm not to good at switch tricks or rails on a board but skis feel way more natural to me. I like the style of skiing more than snowboarding and I enjoy it (tried it twice). I hope to get sponsored some day, so should I switch to skiing or stay with boarding? How fast would I have to progress to get sponsored skiing?
