Well I am not sure what you are looking for. Other then you saying you would like an albino. Males and Female babies run about the same not much difference.
Now this is what I would do. What do you charge for a normal site like that. Lets say this.
you charge 500 for a site like they want then I would ask for a 500 dollar snake at their asking price.
If you ask 500 and you want a snake that ranges more then pay the diffence or see if they will make a deal.
