Be careful buying your Hog Island. Every expo I got to has people selling "100% pure hog island boas", and I'm sure they're not. One of the reasons we want a Hog Island is because they generally stay smaller than a BCI or BCC. Unless you buy from somebody you can trust, you may end up with more snake than you bargained for.
Here's a thought, have you considered a leopard or blood boa? As I understand it, the blood and leopard genes are from the dwarf Central American boas. So instead of relaying on somebody's word, you could have visual confirmation that it is, in fact, a dwarf boa. A lot of those blood/leopard boas are pretty stunning. Price wise, they are in about the same range as a Hog Island from a trustworthy breeder.
I looked at blood boas and they seem like a better option, pus I love the color
