I totally understand. I'm unemployed, too.
A couple of suggestions for you:
1.
http://nashville.craigslist.org/ See the Barter section in the For Sale section. Also Services. You can ask if someone can repair your machine (or give you an old on of theirs) in return for something you can provide. maybe you can make a quilt (or potholders or something) in return, dive them a quilt you've already made, give a quilting lesson, or swap with some other thing you know how to do. Poke around the ads, because there's a free section and a wanted section there, too.
2. Post a paper asking for help on thsi at your local church, same idea as above.
3. Now might be the time to explore hand piecing and quilting.
4. If you're able to sell any of your quilts, consider turning that into a microbusiness and getting a microloan. You can get free help with this at a Small Business Development Center. They're usually on college campuses. Find one near you here:
http://sbdcnet.org/ You may qualify for free (subsidized) entrepreneurship classes, if you're interested. Your state or local government website may have info on this in ther Business section, if the SBDC can't refer you.
