Two different important stages here, and like most things, the more you do it the easier it gets.
First is skinning, go gutting or gutless (now my preference), and removing as much meat as possible after backstraps and quartering.
Second is what takes me a lot more time after the meat is aged a bit. Similar to wapatibob, I remove all fascia and lymph nodes as i separate out by muscle where feasible. The hind quarters are relatively easy to separate out muscles as they are larger.
Elk are easier to me than deer as the muscles are bigger.
The paying a butcher to watch a pig processed is a great idea as are the youtube videos suggested...some of those are bound to be good.
