You may want to contact Steve Pierce, in Graham, TX. It's probably a fair ways from you but at least he's in the same state. He has a website at
http://www.pierceaero.net
Tell him that Jon B. (from supercub.org) sent you.
Otherwise, Tony Markl takes his 'show' on the road. He's in Maryland but travels to do this kind of stuff. He's an old Champ flyer. One thing he does well is education about covering. You can work with him 'til you feel competent to finish the job or he'll finish it for you. He also has a website; I'll try to get his address and post it.
Good luck!
Jon B.
