Kristen,
I know there are lots of people who make money off of their quilting frames. You will just need to practice.
Have you checked Craigslist within a reasonable driving distance to see if someone is selling a frame? You can save a bit of money by getting a frame used. I wish I had known about that before I bought mine lol. I would have saved quite a bit of cash ;)
If you find one that you can drive to get to, you can always sell the machine it came with - assuming it is a combo type of a deal.
