there is a place in canada...called "quilts for sale" they have a pretty good program for you to sell your quilts, finished or not, and prices seem to range from $45----up to a couple thousand, so they have quite a variety.
if you finish the quilts (quilted and bound) you will get 3-5 times as much as you would just for a top, and tops are harder to sell...people want finished products...unless of course they are quilters...
good luck
