It is really beautiful I can see why you wouldn't want 'to give it away'. I totally agree with you quilting for money is a chore. I have a co-worker who has hinted he would like me to make him a quilt. The last time we were in a group he started asking about it, I said I don't think you realize how expensive that quilt would be, and then explained how many hours I put into the current quilt I am making and it's not even finished or quilted yet.
If you ever do it again be up front with the person tell them you'll charge a minimum of $10 an hour and that an easy pattern can easily take 60 hours to make, and I think I would require that they purchase the fabric, and supplies as well that shouldn't come out of your time.
