This thread probably belongs in the 'Misfires' section.
Suggest that you contact Texas Parks & Wildlife and ask them for their recommendations and to put you in touch with a game warden in the county or counties you wish to hunt. They will know who is working as an outfitter or guiding hog hunts in their jusidictions. Another approach is contacting the Chamber of Commerce in those counties for the same services. Most property here is private & leased and to come down for a short hunt you will do much better with a guide for what you have in mind.
FWIW, I've found that feral hogs taste very good [better than a lot of the commercially grown stock] when properly field dressed and cared for. I think shoats are the best, but sows eat well enough too. I do not think you can ever completely cook the 'taste' out of a feral boar, though you might mask it in sausage. Most all feral hogs are lean compared to domestic stock.
