I can't speak for other states, but here in Ca, an packer/outfitter is assigned an are exclusive to them (just like everywhere else). They have assigned campsites, so if someone is occupying the site, the packer has a legal right to kick them out so their party can occupy it. The packers/outfitters also maintain most of the trails they use in their areas (part necessity). In short, they not only provide a service, they have some responsibilities. The packers that operate along the Pacific Crest Trail have the perk of packing supplies for all the foot traffic/backpackers. I say perk because they get lots of business from them, it helps pay the bills. But like others have said, I would not expect much opportunity for an outfitters license. In one area I hunt, the outfitter brings in a party, and moves the animals to another area, and they stay there and hunt until they pack out their clients. So in short, depending on the length of time clients want to stay and hunt, there can be opportunity to hunt while providing services to others.
