I can offer any opinion on Schraders as I have never hunted there, but he certainly can not be as busy as he is without some happy customers??
If you run down the counties in Maryland the two best are going to be Kent and Queen Annes. Cecil in nice, but there is alot of pressure up there and it is a rifle county. Lot's of deer harvested that do not reach potential and probably the number one poaching county JMO. Kent and Queen Annes are nice as there are some larger tracts of woods but super expensive. Talbot is very developed and while it has lots of large farms, many of the mansion type, waterfront places are not hunted. Caroline is very nice as it is the least pressured and still somewhat affordable. Dorcehster, Sommerset, Wicomico are even less expensive and get less pressure, but the quality of ground is far inferior to the upper short. Pines, instead of hard woods, and soik quality (yields on farms) is much lower. Lot's of the area is marshy and while it makes for good cover, not so much to grow a dense population of big deer.
So if you look at Kent and QA counties which most are thinking of when the consider ES deer hunting, a good farm is going to run $10,000. Maybe you can get but a few 150" deer on that farm each year through some aggressive habitat programs and QDM practices. Adding on insurance, hanging stands, guides time and profit you will need at least $15,000 in revenue. At $250.00 guided hunt cost per day you will need to have 60 hunts. If everyting is perfect, you will have two happy hunters that will shoot a big buck. A 3% success rate is pretty darn tough.
Due to the cost of the leases, I think a trip to IL or OH makes more sense. The same $10K in lease cost get 5x the land.
