I would contact Pristine Adventures/Larry Barrett (google Pristine Adventures)in Fairbanks, Alaska and have him arrange a DIY trip to Northwest Alaska and the Kogzebue area. I think in the end the costs will be about the same.
The Alaska Pennisula and the Mulchatana herd have suffered in the last 5 years. The other way would be to fly to Fairbanks and find a agency that would rent you a truck and allow it to be driven on the haul road. There are several 135 fixed based operators that can fly you out or one can hike the 5 mile distance from the road and pack their bou back. I have done it several ways in the last 40 years; today it is not cheap as there are a number of people wanting that experience which causes the FBO peices to rise. Do it, it worth it.
