I've used Huntin Fool for a while and they do a good job and are certainly personal with it. You can call and discuss at any time.
Aaron Neilson is a great guy and I would trust him as well.
Nosler's Magnum Hunt Club is also a group that I know well and they do a good job with apps too.
Altimus run a great service and will front all of the money for you like Cabelas but he's a little more expensive than some others.
I'd stay away from Cabelas and USO. There are several more that I've missed but the smaller operations seem better and allow you to have a lot of control over what gets done without the headache of keeping up with everything.
