Any qualifed taxidermist can supply you with a Beaver mount. The rug pictured is very easy to do, but it doesn't look like the backing was sewn, just glued to the skin, can fail down the road. Add the legs and tail for a more conventional rug.
PMs answered. Ive gotten quotes from 300-700 to do this type of mount. The tail is on there for anyone looking. Still shopping around for the best deal and quality work. Im located in central NJ and i have about 2 months till im going to do it.
