I was successful last year on my dream hunt for Dall sheep and I left my head with Joe Romero in Anchorage. I did a lot of research on taxidermists from that area and his name came up often. It was hard to leave the horns in Alaska tho! Should be getting the mount within the next month. Can't wait to hold those horns again!
Good luck on your hunt and like others have said, take your time and enjoy it. It goes by way too fast!
