Don't know where in New Hampshire you are, but if you are near the seacoast region:
http://www.britbits.com/ for parts. They have some used, too.
Really it sounds like the only repair for that turn signal switch is replacement.
Agree with Doc on the dash, unless you want to replace the whole thing. That's when shipwrights disease sets in. My 74's been cracked for years, but it's a driver. For a quick flip, you'd never get back what you put into the repair, if done right, in my opinion.
Like Doc said, also, depends on the wheels. I repainted my rostyles, but it is tedious, all the masking. Came out nice in the end, though. Used Duplicolor Ford silver & Rustoleum semi gloss black. Has held up for over 20 years.
Value? Wide open without actually seeing it. At the top end of Doc's range, it better be end-of-the-world California car or similar. Bottom of his range is something like mine, a well used driver.
Hope this helps.
