I dont have any experience with the business side of things but $10,000 sounds kind of low for stock+supplies. Stock alone I would think would be more than that. Figure you need probably 20-30 of each baby BPs and boas alone. at about $50-100 a piece probably. Although breeders probably lower the price a little for a larger order like that. And thats just 2 species alone right there, not talking adults or anything which run more expensive, or any possible morphs. Needing a big enough initial supply though so that you dont run out too fast. Especially when you talk about having other animals in quarentine right after the initial stock you open the store with so that they are ready to hit the store in time after the others are sold without delay. You dont want to end up feeling rushed to resupply the store and rush quarentine and risk losing a store full of snakes. Just taking that into account though Id say stock alone would rise above $10,000. I have no idea how much supplies cost for that kind of stuff, but its not cheap either obviously.
