It is very difficult to put a value on a quilt. For just straight stitching, 3 cents an inch is high even in my area of So CA. The few LAQ charge 1 cents for an overall pattern. Depends on your area. You might want to do research on fabric stores online that may have some quilts for sale. I have known a few quilt shops owners, and their samples rarely sold for the price they should have. I use to quilt for others on my Bernina 1530 over a decade ago, and I charge $8 an hour. I kept track of my time signing in and out on an index card. Good Luck !
