I have a cheap ATV winch mounted to the wall of my garage, pulley chained on a rafter and pull it up.
So no one complains about blood, I use one of those cheap kiddie plastic pools and put it under it like a drain pan.
I have pretty much the same set up, except I have my pulley bolted down in the rafters.
I use a small wheel barrow underneath for the blood. My hose/water are a ways off, so I just take the mess to the water.
