I learned as a kid, watching my Grandfathers and my Dad. I inherited a bunch of skinning / butchering knives, meat saws, a scale, and an old wooden block / tackle / hoist set. If it's cold out, 40 or so, I'll let the deer hang in the garage with the hide on for 5 or 6 days. This year, as I tagged out on opening day and it was 65 to 70, we (my 7 y/o and I), did everything at once and my wife vacume sealed it up that night. It's not that difficult to do if you go slow and if you pay another to do it, you risk not getting the best cuts of meat. Nothing like fresh tenderloin, butter, onions and cold beer after the job is done!
