with 26 recognized herds in this state, I think personally you could have just as good of a hunt for a potentially cheaper cost, depending on what your flight to deadhorse actually runs or for that matter the bush flight out of deadhorse (which is typically pretty spendy for what you're actually getting). Happy valley is the next hop out, which again isn't cheap. 70 north and deltana offer drops, but alas getting their is an issue, without a locals help or a rental. If I remember right Jeff is out of Kavik, so I'm assuming he's who you're flying with? Would make sense on the hop to deadhorse.
I would think the hop to deadhorse would be 15k miles which is what most (not sure about all) instate mileage tickets run.
Cold foot on the south side is your next hop spot, again tough spot to get too, you could turbo prop from Fairbanks for a fee from wrights I'd bet.
Get a pick up on the road from bettles, or there's a couple guys with cubs on floats doing drops from the same lake...but again you'll have to rent and drive north, pay for the pickup and return. It does open up bettles and the western brooks, WAC herd. I'm not sure how far east Jay flys (brooks range aviation).
Next spot is Fairbanks...which affords you to access to a bunch of herds, western and porcupine in particular, along with 40 mile country being relatively close by, 40 mile can be jumped from delta or tok as well, with tok being the best option, all paved roads which means no issues with rentals. Procipine you'll likely jump out of ft Yukon and out, you can easily get to most of the villages.
Fly into anchorage and you can hop out of their as well.... I have a hunt on my radar out of anchortown a buddy put me onto years ago with an option for moose as well.
LOTS of options for caribou! LOTS!
