Tips for getting sponcored snowboarding?

I need some tips for working my way to getting sponcored snowboarding. What tricks should I learn?Also where I live there are NO hills. We have a small one in the backyard that I snowboard on. In the winter we go over the bridge to the USA and snowboard there. My point is that there are no ski resorts were I live. How can I get better and get sponcered?
