The best I know of is Larder's Upholstery in Homer, Michigan of all places. Mark and Andrew have done many top drawer classics and have many, many concours wins under their collective belt. It is a bit farther away than you want but you won't be disappointed with the work. They have even done a few Franklins! I believe their phone number is 517-568-4035. Let me know if you need any other info.
