I have paid once. After comparing the quality - I have done every other deer/elk myself.
Here's the cheap and easy way. Bone the deer out in the field, get the meat in a cooler - it'll all fit in a mid-sized cooler if it's a small deer. A boned out small bull or cow elk will fit in a 160 qt cooler boned out but two smaller coolers are easier. At home - pull out one piece of meat at a time, cut it up into steaks, roasts, or stew meat. Wrap in plastic wrap and then lined butcher paper, then freeze. If you have a grinder - grind some, otherwise you can always tenderize or dice stuff small for certain dishes. No equipment required other than a cooler, knife, sharpener, cutting board, plastic wrap, freezer paper, tape, freezer space. I try to cut as many steaks as possible as we grill a lot - year round. I always run out of steaks before I do roasts, ground, stew meat, etc.
Small bucks and does I've gotten ~50lbs of wrapped meat. My most recent small bull was about 180-190 boned out meat, but not cut up and processed.
My bill did go up significantly this year - but that was to purchase a big dedicated grinder and a sausage stuffer... Already have a chamber sealer.
