The Amish in Middlefield, OH do hand quilting for quilters. (All of their quilts are hand quilted.) There must be a market. The best way to get your name out would be to advertise at your local quilt shops or message boards around town....Get a good photo of your work.
If you don't try you'll never know and if you try you may be overwhelmed. I hope you're overwhellmed! Good luck to you!
