I've been to the place that you are taking about, I had a good time. I took a group of guys from my church and everybody seemed to have a good time. Since it was a free hunt for a church's mens group none of the staff was there except for the caretaker, so I could not tell you about the cooking, or hog cleaning.
I have seen that work for the hunt and I have been thinking about it myself. Even if you work for the place you are still going to spend over $150 for all of the extra fees... Still a good deal.
The hunting is a high fenced place, but that does not mean that it is an easy hunt or anything like that. We saw plenty of hogs to make it fun, the largest taken by my group was a 200+ sow. The only people that I would see is if you are not the only person/group there then there might be a mix of gun hunters and you bow hunting (I am assuming). PM me if you want more details or want to talk to others that went on the hunt.
