Yeah man go check the Junior Freeskiing Tour if you are under 18. I think those comps are full but there are a ton of regional ones that you could do.
I don't know very much about the availability of adult ones but I do know that they have adult comps at Kirkwood, Crested Butte, and SnowBird. For those go to the Freeskiing World Tour website.
Have fun man!
