You might find someone willing to trade a Texas hog hunt for a South Dakota bird hunt if you offered that up.
This is a good start. ^^^^^^^
You're just probably not going to find a free hog hunt.
You will find places that charge day fees and provide free camping or cheap bunkhouse use and let you hunt on your own.
Some good hunts offered in the outfitter section, you may be surprised what all is involved in taking hogs consistently. A few hundred dollars would get you on a place with patterned hogs, if that's possible, stands to use if wanted and feeders if wanted.
You should inquire with some of the hunts offered here and talk about what you are looking for.
