At .01 per sq in your size is just over $104 quilting only and usually pantograph quilting only.
.03 which is more the range for custom quilting as opposed to pantograph edge to edge would be around $312 quilting only. Ask to see the work of the quilter especially for custom since that can vary much more in skill and quality than the panto quilting does. I do panto only right now and am hopefully going to venture into custom over the next year and know it is more time consuming than the panto. Maybe you'll be lucky enough to find great custom quilter for less--maybe barter? Remember there are additional costs sometimes for thread, batting, etc. Ask ahead of time. Good luck with the DWR, they are beautiful.
