Instead of getting a huge loan on all those common snakes, why don't you slowly invest into multiple gene females and a few visual recessive females? Raise them up for a year or two then buy multiple gene males? I understand your excitement/hopes for a breeding business but you have to be smart. All of those snakes you listed are fairly common now and the prices will plummet in the next 2 years. It would probably take you 2-4 years if your lucky to be able to pay off that loan just from profit of selling babies.
