If there is a guild in your area, you can join and let folks know word of mouth. Another great idea is to do a bit of research to see if there is a group that does charity quilts near by. They are usually looking for donated long arming work. You would donate your time, and usually thread, but you get to practice and this also gets your name out there. As far as pricing, it varies by geographic region and what type of quilting you are doing, custom vs. panto/computerized etc. Check with local long arm businesses in your area to see the going rate. I got a long arm a couple of months ago and was not planning on doing any 'for hire' quilting, however, several folks have approached me and asked if I would do their quilts. I need to feel that my skill level is sufficient, but I probably would take a few jobs. My theory is that I don't want my hobby, which I love, to become a job.
