Designing my skateboard

My 20 time project is designing a skateboard, I choose this because I've skateboarded for a long time so I wanted to do something i actually enjoy. The main audience I'm targeting is skaters or anyone with a interest in skateboarding. My main resources will probably be skate shops, Hopefully this shouldn't be all that hard all i really have to do is sand down the deck, spray paint my design on the bottom and buy trucks, wheels, bearings and the hardware to hold the trucks to the deck. I'm most likely going to start this weekend.
