Try doing as much of the work as you can yourself. I've done a couple of cars, and only farmed out the final paint job. Remove all the glass, rust lurks under the window trim and gaskets. I've used a body grinder to remove the paint, (you must have a dry garage and be careful). A little zipstrip works for the hard to reach areas. Qtr panel replacement, you might try find an experienced welder to give you a hand. Bodywork take a little patience, and hard work, but it's worth it. Use your friends as sources for info and help, (maybe even your brother in law). You'll save a ton of money.
