I live in North West PA and some of those prices seem high. I would have her pay for fabric, backing, batting and pattern.
Then estimate how much time you will have involved to make the top and quilt it and charge her accordingly. Long arm quilters in this area charge anywhere from .01 cent per square inch to .04 cents per square inch. Custom quilting is usually the .03 to .04 cents per square inch depending on how much quilting is involved. It is hard to charge relatives, but if you don't you may be quilting for everyone else and not yourself which may takes the JOY out of it for you. (Of course, that depends on whether you want to make money at quilting or just keep it for a hobby with no pressure ... only you can decide that!!)
