The logistics of dealing with meat and cape/horns is a pain.
If it was me, I would flesh and salt the hide in the field, keep the meat with me in the field. Then fly all the meat back to Anchorage when I go and drop it off at a processor and pray they have space and have a backup plan. Many fill up and don't have room... even if you have the grocery store do it would they get it done before you leave? That will be a very expensive shipping charge from Dillingham.
Much of the meat taken by NR and some residents, hunters gets donated, due to logistics and more often, due to costs of getting it home. People will spend $8-10k bit not another $1000 for the meat. The locals that get the donations are more than happy to take it though.
Sure there is an opportunity for a business, if it was viable there would be one. Note what I said before. Most NR are here for the antlers and adventure, meat is secondary of they won't pay to ship the meat they aren'tgoing to pay to have someone do the logistics. I know a guy who tried to do this locally, and couldn't make it work. In the biggest market in the state...
Many transporters don't want to deal with the whole transfer of possession issues, and maintaining other peoples meat. It's a full time job and added cost.
