Packaged and frozen meat will not compact very well into a cooler so you are going to need quite a lot of cooler space. My guess would be about five 48 qt size coolers.
200 pounds is probably a good estimate for a cut/wrapped Eastern moose. A very large Alaska/Yukon bull will bone out to 600 pounds in the bush and after professional cut/wrap job will net at about 500-550 pounds.
