RE: butchering...
I do my own unless I have the deer turned into sausage links. Thats when I pay the man. I bought a Foodsaver and package everything into usable portions and into the freezer. The meat stays freezer burn free for a very long time if not for ever but it gets cooked so I'll never know that answer.
Most of the time I will take the deer to a locker and hang it there a day or two so it was good and chilled. By doing this the deer comes apart much more easily and you can recover from you hunting trip for a day or so first. I ususally process my meat in the garage and have something fresh off the carcass on the grill. I shot a hog a couple weeks ago and when I was buthchering I had a rack of ribs on the girll. When I was done and all cleaned up the ribs were done!
