Most of the rino hunts today are with tranquilizer guns with a flock of biologists tagging along. The price to hunt rino is not the norm since almost all if not all is done on huge game ranches and since rinos are not prolific breeders they are expensive to hunt. If not for hunters there wouldn't be any rinos left since the horn is what the poachers want, to sell to Arabs for knife handles since it is a status symbol and orientals for folk medicine. As you mentioned, most of the meat goes to villagers for both food and to make biltong out of and sell in the markets, they get both food and money from hunter killed game. Hunting makes it worth while for the African villagers to help protect the game rather than poach it. It also provides employment for them.
