Unless you're shooting them from a helicopter people should nearly be paying you to hunt them. You pay whatever you're comfortable with but there's plenty of people who would let you do it for free.
I say this as a resident of Texas. No hunting license is needed, any means of taking game is allowed, can be hunted using thermal imaging optics and/or night vision with IR laser, suppressors are highly encouraged and so are fully automatic firearms. It's quite literally "anything goes". Heck I've seen people run them down on a side by side because the passenger couldn't shoot them all fast enough.
Bob Elliott at 940-782-1079 is a guy who does hunts in North Texas.
818 Ranch is $300 per person, unlimited hogs, 3 people hunting party max, 3 days and that price includes lodging. if you shoot a boar hog bigger than the ranch record you get $200 back. They also offer deer hunts for very reasonable prices if you wanted to snag a 2-fer while you're there. Not sure on where that one is located though.
If you're on facebook I'd recommend joining Texas Hog Hunters Association FB page and then just reach out to people on there. All kinds of people constantly looking for people to come to their property to hunt hogs. Usually for free but sometimes a small fee. If you want to pay $400-$500 then just google "Texas Hog Hunting Ranch". I found some not far from NM doing that but they are more in that $300+ ballpark.
