Are you looking for a rack that 'hangs' on a hook? Or one that is literally 'mounted' to the ceiling? For starters, you can try My Favorite WEB Search Engine. From there, you can sift through the links. And once you get a link that has ANY type of wine rack, consider e-mailing them with what you want. If it's a specialty item, perhaps they can order it.
On other idea is to contact the Food Service Managers a local hotels and resturaunts. Perhaps they have some Vendor Catalogues you can peruse. These magazines have all types of ads throughout and in the back. Hey, maybe the Manager knows exaclty what you want.
Other than that, I wish you well. My best to ya and hope this helps.
