I know that Stitchin' Heaven has a Quilt Owner's Boot Camp:

Good luck whatever your choice. It's tough starting a new business. I would also consider doing a survey on what people might like. I noticed that some stores carry a large variety of fabrics while others focus on only a few types. Do you have some good teachers in the area? How close is the nearest quilt store to your area?
