Will exhchange hard work for sanding training...

I am looking for someone to train me in sanding surfboards. While I don’t surf myself, I spend many hours videotaping friends and family during their surf sessions. I live on the Oahu south shore. I am versed on the variances of surfboards and am interested in learning the work from the ground up. What better way to start than sanding? I am willing to work for FREE for a couple of months. I’ll even clean the place up after a training session. If you are willing to use my hard work, please respond to this thread. Mahalo and aloha!
