I'm pretty in line with Mick. Back in '88 I bought a '58 C-182A that was sitting in a farmer's field with (literally) chickens roosting on the back seat, the wings off and stored in an old barn, paint peeling, and the motor knocking. $4k. It obviously wasn't flyable home, so I got a local IA to put in new control cables, new bladders, and found an off-duty Navy painter that was a wizard with the best grade automotive polyurethane I could get. Made a paint booth in an old barn with plastic sheeting. Motor knock was a busted starter adapter. Flew it home (500 miles) on a ferry permit with pillows over the open springs in the seat and a handheld for whatever comm I needed. Spent two years going over every blessed inch of the machine from spinner to tail light. Got an Airtex interior that made it pretty damned close to what came out of Wichita in the '50s. Crates of chromate primer and interior paint. Swapped some stuff I didn't need for a couple of old but reliable King KX-170s. When I was all done I had (have) $25k in it. Put a thousand hours on it and my widow will be the one that sells it.
Yeah, I was and am an A&P/IA, so I could sign off a lot of the stuff, but there are two or three of the same breed on the field that will let you do most anything LEGAL you want to do for a bottle of good scotch or a case of good beer. Small town airport, easy going. Besides, log everything you do (including crap like this on the internet where you are getting advice and information) and get that same A&P to sign a letter that he attests to your work hours and you can sit for your OWN A&P after 30 months of full time work on your own airplane.
