Dont know what the hunting group does in GA but here in Texas it is real money. If you do quail you can do dove also, guys pay almost as much and here the season is different. Turkey and quail kinda overlap in the spring here. Not sure of the seasons there.
IE, have a friend who owns 6k in south Texas and charges 15k/whitetail deer. Over 200 is 25k PER deer. but you need a year round manager to make sure you have 200+ deer. The temptation is hard to resist for some hunters. Anyway, he makes 500k - 800k year GROSS. but he also has !00k for manager, 50k for hospitality manager and about another 100k for seasonal cooks, cleaners, and groundskeepers. The good news is that deer season starts in Oct. with bow and turkey season ends in March here. The rest of the season is just groundskeepers and wildlife management (it is a year 'round job for a good one).
If you are going this way maybe I can get more info for you on the numbers.
