Owning a taxidermy company, I am trying to be on the defence of the taxidermist, however, your time frame is a tad to long even for a world class taxidermist. I strive to have a turn around of 12 months or less, unfortunately my own time frame was broken, just grateful its with a good friend who is understanding, as it has taken almost two years to get some scraps to do a repair on a zebra hide. None the less at this point I would suggest going to the taxidermist and retrieving your hide and antlers, and try not to be to disappointed if you do not get the original hide back or the hide is buggered. That's a long time for a hide to be frozen and can guarantee there will be burn on it. I am trying to see the bright side of things and hope there is a mounted elk waiting for you in his studio. best of luck
