Sponsor me video "for skateboarding"

I'm in the process in making a sponsor me video and if you don't know what that is It is a video where you try to get sponsored by like a skate shop or even some skate companies. I know it is going to be difficult to even become AM but I could use the challenge. I am going to greyson skate park this weekend and I am going to try to start the video there. I am going to try to pull off some sick tricks but I know that there is going to be a lot of screw up's!!!! Anybody that knows of any good places that could use an AM "amature" let me know leave me a comment!!!Please!!!
