I don’t know of any dive shops near you other than the one in Rutland. I recommend you go to the United Divers of New Hampshire web site www.udnh.org and put a query out. I think there was one in or near Lebanon, NH, but that would be still very far. The down economy has shut down a lot of dive shops. Another possibility is a dive shop in or near Keene, NH; that is still very far.
I think the shop is Rutland is your only hope. If you pass through Southern NH going to dive the ocean in Maine or NH, there are a number of shops. One is Divers Den in Manchester; another is Atlantic Aquasport in Rye, NH. If you want the names and phone numbers of other Southern NH dive shops, should you be passing though, let me know. Willis
