Covert Outfitting is who I went with. All in (tags, fuel, tip, etc) was about $9600 but that cost was driven up due to the Shiras portion and guys trying to fill their North American 29.....
Kiff Covert will have a booth at the Washington Sportsmen's Show in Puyallup.
With that said, if you want to kill a shiras moose it was definitely a fun hunt with plenty of moose around and not overly physically challenging. I went the last week of November and would probably move that up a week due to the allotment of tags per unit and the risk of tags all being used in the best area before you arrive. (4 tags for 3 different units with a total of 12 tags, once the 4 tags are filled in a particular unit the guide can no longer take anyone in there)
Any other questions feel free to PM me.
