Where can I learn how to snowboard? How much will it cost? And how much is the board and suit?

Every since I saw Shaun White, Gretchen Bleiler, Kelly Clark, Hannah Teter, Seth Wescott, and other magnificent snowboarders at the olympics, I wanted to learn how to snowboard. It looks so fun, and hey I might train for the next olympics if I'm capable...I got four years.
