I don't know specifically, but there are a lot of good hunting along the Sulphur River. That is where I would look if I was looking for a lease. There is also some government permit land in the Bryans Mill area - so you could do that if you cant find anywhere. My brother-in-law's family land is adjacent to that, and they have some pretty good hunting every year - especially hog and duck. It can be a little crowded during deer season though.
You may also want to check out Broseco Ranch. It's sitting right at the fork of the Sulphur River and White Oak Creek. I know they do guided hunts on that land, but not sure about leases. I know the guy that is in charge of their wild game - good guy. Just google Broseco and you should get their contact info.
