I don't know who guided you on your Okla hunt and am sorry that you feel you were ripped off. I happen to live in far south central OK. I live adjacent to a 7500+ acre WMA (Wildlife Managemnet Area). There are lots of hogs in this area in fact (The Game Dept has been shooting them from helicopters at landowners request)they are so plentiful. Landowners routinely spotlight them off their fields at night.
The only license needed is a state hunting license and there is no limit or special license needed.(NOTE: This is NOT hog hunting under a feeder from the comfort of a blind) If you are willing to get into the river breaks and sloughs and work for your hog you will find what you are looking for. Also this time of year the farmers are planting winter pastures mainly wheat ryegrass and clover/oats and a proven way to score is to locate a trail coming off the WMA onto a planted field and ambush them coming and going. If you are interested in a hunt like this I would be happy to show you around free of charge. Of course lodging and meals would be your responsibility as well as your expenses. PM me if interested.
