.I might even start them at $7500
To be honest unless you gain some reputation by than I don't think I would even buy them for $1000
Hets are a though sale, if no one knows who you are and you have no reputation people are not gonna take the risk.
My advice to you start building your reputation NOW, sell some visuals over the next few years, give back to the community, and by than people will be more willing (if interested in that project) to invest with you.
And remember don't count your "snakes" before they hatch, lots of thing can go wrong, breeders being picky feeders and not growing, breeders not breeding as fast as you want them to, slugs, problems with hatchlings etc
