so I can develop a skill that isn't available to me in the secular world
You're trying to learn how to brainwash people into submission to a cult? You're trying to learn how to suppress your thoughts and brainwash yourself, ala 1984? You're trying to learn how to stand in front of a room of slack-jawed retards and regurgitate tripe from literature written on a 4th-grade reading level? You're trying to learn how to knock on people's doors and present a bait-and-switch message of Bible education then give them Watchtower dogma instead?
If you want some insight on how to start a cult or run some other sort of con, this might be one way to go. But you're going to have to deal with a bunch of sociopaths and busybodies who will be scrutinizing you constantly for something to complain about. If you're not in it 100% and drinking the Kool-Aid or willing to constantly live a lie around them, you're going to be miserable.
If you're going to be there anyway, you might as well grab a girl. While they're not as slutty as most women (better odds of no STDs and no kids), they're not the prudes (at least in my experience) that they pretend to be. Because of the lack of JW men, you can marry up and she might be nice and 'submissive', if she's been indoctrinated enough.
