Oh my god, I so know what you're talking about--I've been hunting endlessly for days, trying to find a female snake to maybe breed my male BP to someday.
They are EXPENSIVE! Females more so than males.
There are barely, if any, breeders where I live, so I'm mostly looking online (unless I want to pay $80 at Petsmart/Petco for ONE BP). Shipping sucks, and unless you save up enough to get more than one female at a time, you'll lose money paying it.
Also, you need to get more than one female to breed your male to. Well, ok, not NEED to, but you get it. If you want to at least break even on the snakes you'll buy, you want as many offspring as possible--so I'd say for every male, probably have 2-3 females to breed him to.
Also, plan for the fact that people may not jump to buy your baby snakes at first. If that happens, what will you do for housing them? Housing multiple babies in the same tank could cause them to refuse feed, and downright stress them out.
I agree, though, that they are addictive little buggers.
One more thing--perhaps instead of buying a snake right away, you should save up for a while (if you can, I can imagine what college must be like) and see if you can get a more expensive morph, i.e. bees or Super pastels, lemon blasts, etc. That way you could sell them for a little more, too.)
