alot of times you can go to an ama club for a time or two without having to join. You could see if someone there was up for private instruction, or could work out a deal with you.

just incase that sounds like something that might work here are the links
http://www.modelaircraft.org/clubsearch.aspx
http://www.rcuniverse.com/clubs/

on the second one you can find people here on RCU that belong to clubs close to you, and they might also be helpful in finding someone to help you out. GL
