I don't know how much prior experience you have with owning snakes, but I would highly recommend you have a few years in before breeding. You should assume that you will be keeping all the snakes you hatch out for life, because there is not guarantee they will sell. As for hot, white snakes seem to be very popular. So a lesser/lesser or lesser/mojave pairing could be a very economical way of producing "white" snakes. Whatever you decide good luck and do your homework.
