RE: processing your own deer
My family butchers 2-3 a fall along with a hog (to mix with the burger and the sausage).
We still send 1-2 to the meat market in town which charges $300-$400 per deer (70-90lbs of venison)depending on what you get. We like to get a lot of snack sticks, jerkey, brats, summer sauage, etc.
