Once you learn the technique all you need is a meat slicer, grinder and I recomend a vacume sealer. They keep the meat fresher longer. We process our own deer but some of the members in our camp pay to have there deer butchered and here it cost about 75 dollars a deer. So 150 sounds pretty steep to me. But it depends on where you live. But I would still go back and ask the butcher where the other meat went cause it doesnt sound like you got it all.
