Whats your budget? You won't find much in the way of a transported hunt for less than $5k, if you can find one. Plus your expenses to get here.
The haul road is basically your only "in expensive" option. Bow hunt along the corridor, or walk in 5 miles off the road.
The word on the street is the 40 Mile quota will be around 300 this fall. There are limited spots with transporters already, and the quota could be filled early, meaning a shorter season. The closure in the NW will keep you out there (and its not cheap either), other flights to the eastern Brooks are expensive $3-5kpp easy, and really no other options outside the haul road corridor.
Caribou populations are half what they were 10 years ago pretty much statewide outside the eastern Brooks.
I wouldn't' be surprised to see guided caribou hunts start going for $20k and restrictions put on NR. Guided hunts are already pushing $15k.
