I would suggest that you contact the office of the Altamaha Waterfowl Management Area at Darien, GA. This is a state management area operated by the Georgia Dept. of Natural Resources. A number of the islands in the Altamaha river area are in the management area and in years past had a heavy population of feral hogs. They can probably assist you in your quest for information on the outfitter as well as the general area.
