First of all, this is a wonderful piece of work and best of luck in finding a quilter to finish it for you. I would find the best quilter you can find to give a quote on the price of quilting. I would get picture out to some of the places others have mentioned, especially Tom Hiddleston. He will be very impress with you work and might even offer to pay for the quilting. If that doesn't work, you might get interviews with magazines and television and earn some money to pay for the quilting. And when finished it should be entered in however many quilt show as possible, you're sure to win.
