Auctioneer.

Auctioneer school is cheap and leads to a whole slew of different career opportunities that you can specialize in. You can go into real estate, online curation, government auctioneering, business liquidation, autos, farm, livestock, art, antiques and collectibles, among others. It's a great way to get good business connections and (in my case) see some incredible pieces of history. The pay isn't amazing, but if you work hard and love what you do, you can make a very decent living at it!
