I normally process 3 deer each year with a lot of help from my wife. Living where cool weather is a pretty sure thing helps a lot since they can hang for a while until work, family and other priorities allow you to deal with em.
A buddy showed me how about 10 years ago and we've done them all since. No expert here but we get it done and it's all delicious. I would never go back to paying someone to process my deer - like someone said it's just the next natural step of the hunt and has become a family tradition. When our kids were still at home we'd involve them in packaging and labeling too.
We use the grinder attachment for the KitchenAid mixer and it works great. Getting into making jerky, snack sticks, and sausage too - guess the next step is a smoker!
Brought 2 caribou home from Quebec in late '07 and did those myself too - absolutely delicious. Hope to butcher my own elk and moose someday too.
Sam - This is definitely something you learn by doing and will get a little better each time. I like this instructional thread - lots of good info:
