I'm doing a DIY black bear hunt on Kuiu Island this fall (so I can combine with deer and wolves, if I see any). This will be my first trip to Alaska, so I don't have much advise other than:
I'm guessing you are talking about blackies, a quick google search will turn up more outfitters than you can shake a stick at. You can check a few of them out to see if they have references listed (or request references) and call some people that have been with them.
Will be curious what Kodiak has to say about it.
