I dont know of any outfitters either. I do most of my hunting on private land, but I do enjoy hunting state land too. You can do a search for NYSDEC, look for the public lands locator link. You can get a lot of great info from there...topo, access points, trails, etc.
Depending on where in Mass you are, the Catskill park is not far south of the berkshire spur of the NYS Thruway. Might be worth looking into for you.
I have some NY Game and Fish Mags somewhere....they list outfitters, I will try to find them.
