Looking for a beginner board For my son.

Hi, I was hoping someone might be able to help me. I have a 15 year old son with Tourette syndrome, things don't come easy for him, but he learned how to surf this summer, I have never seen him so happy as when he was surfing, I think it was very theraputic. I am a single mom on a very limited income, but would love to get him a board. We live in the Southern California area. Can anyone hook me up with an inexspensive board, or a board that they are no longer using and would like to donate? I would be so very grateful to anyone that can help. My email address is kreinbrat@aol.com
