If you bought those snakes as an "investment", then you made a major mistake. Any snake, even the mighty BP, is miserable as far as investments go. Can you make money? Absolutely. Is it "easy money"? Nope. You have to feed, clean cages, produce, market, and generally work your tail off. Even if you make money, compare the amount of profit to the hours you put into it, and you'll see that delivering pizzas would have been a better use of you time. If you wanted an investment, I'd reccomend a diversified portfolio of mutual funds.
I'm a small "Joe Schmo" (as I think you put it) myself. I work really hard to maintain my collection in addition to my family and work responsibilities. I've been producing BPs for several years, and I've sold every baby I ever wanted to sell. They sell. People will buy from you...they've bought from me. I've now sent snakes to people all over America (Illinos, Texas X3, California X3, Michagin X2, Minnesota, Pennsylvania, Florida X2, North Carolina, Kansas, all over my home state of Virginia, a few places I can't remember at the moment) and even to Puerto Rico. Many of my babies I simply wholesale to local pet stores. This year I probably sold about $2500 bucks worth of snakes. I probably spent close to $2500 bucks in rats, electricity, papertowels, facility upgrades, trashbags, advertizing, shipping costs, etc., etc. If produced higher end stuff, I'm sure I could turn a handsome profit, but it would still be small when looked at from a dollars per hour standpoint.
I enjoy my hobby, so I feel like I came out ahead. I'm investing in my home, and I work hard at my job to earn a buck...
