I have a similar problem but not quite as large -- onthe other hand, I am nearing 70 so you may have more time than I to solve the 'problem.'
I think finding a group that NEEDS quilts or needs to quilt, might be an answer. If you felt that your work was appreciated, it might be esier to let go of fome quilts.
If you find a group of folk that might need lessons (homeless shelter, migrant workers), you could start by teaching a class, giving lessons and the fabric to work with and the irons, etc to binding, there you are. 'teach a man to fish ..."
When someone gets to the binding part -- there you are, someone to do the binding.
Good luck on this and please report on your progress.
