Deadwood Outfitters -
http://www.deadwoodoutfitters.com/Tom & Dawn Carter - good people, have spoken with them for several years here at the Great Eastern Outdoors Show. Several hunters I know locally have used their services with good results.
At least two groups that I know of, I'm in one of the groups, are going out this Fall with them for elk. Most in the groups are repeat customers.
PM me if you want.
