Future snowboarder, but needs some help.?

ok, im 15, a sophmore in highschool, and live in a small town in Texas, nowhere near the snow or any mountains. Ive been snowboarding for about 3 or 4 years on and off during vacations to places like.. breckenridge, CO. angelfire, NM. camelback, PA. and more.. once i got the hang of riding, and started getting good, hitting kickers and rails, i knew i wanted to make a career out of it. The only problem is that i live so far away from any snow, and wont be able to move till i get out of highschool. Money is tight for me right now, so i wont be able to hit the mountains for another year or two. Any ideas for what i could do? or if you know a place that i could snowboard for cheap? Im trying to do all i can to be a better snowboarder.. ive been working out atleast 3-4 times a week, ive even taken one of my old skateboards, bolted some shoes on it and been practicing grabs on my trampoline. Im set on snowboarding, its pretty much my dream, if you have any tips for me to progress faster or fun places to ride, please let me know.
