I'll give you a rough estimate for what I did.
Build rack $200(heat tape included, and tubs)
Bought a rack from rb bc build was too heavy-$300
Divider for rb rack-$16 for 2
Thermostat $350 (herpstat 4)
Albino female $350
Pastel lesser female $675
Black pastel female $450
Still need a killer bee male($1000) a firefly female($900) and another 2 gene female($800-$1500)
And I will need another rack for my females when they are full grown. Plus an incubator.
This does not include food.
But it all depends what you want to breed. My suggestion is to start getting you females, and in 2 years they will be close to breeding size, and it will not be such a heavy bill if you space out what you need slowly. I take $100 out of each paycheck and put it toward my snake fund so when I want the snake I like I can buy it with out having too worry how much it cost. But start slow and if your in the bp game to make money right away, you will lose your money real quick.
