I am looking at doing something like that also. I am trying to take some classes either this fall or next spring. There are also several taxidermy schools that you can go to.
Igot a bunch of taxidermy books from the libraryand ordered some magazines off the interent and just started reading up and I did my first mount last winter after I shot my button buck. I dont think its that bad but I think I can do better.
Heres are somelinks to sites that has information on schools if you are interested.
