I am a beekeeper and have developed a near complete immunity to stings. Since they don't hurt as bad, a beekeeper may be willing to do the job for much cheaper.
I knew a beekeeper years ago who was also immune to the venom. He would actually force the bees to sting his hands to, what he claimed, help his arthritis. Not sure how true that is, but it was pretty freaky as a kid watching an old man force a bee to sting him.
