I butcher my own. The problem with most places is that they cut through the bone with a ban saw- that makes the meat taste gamey. Plus if you have sausage done you won't know who's venison is in it as they usually put it in a pile and do everyone's all at the same time.
I did find a place that makes your sausage in separate batches. Ptaceks IGA in Prescott, Wi.
For $80 - complete deer processed (hide on - gutted - of course ) - you pick up packaged meat. If you want sausage you pay for extra pork that they add.

If I didn't already butcher my own deer - I'd have them do it for me. They will make sausage for me this year. Their recipe is better than mine was, so I will just have them do it their way.
