While your business may be working out well for the time being Eric, I think people here are trying to help you see the weak points of doing things the way you currently are. When you are brokering animals you are putting a lot of faith and fate in the hands of your suppliers- who may make mistakes and then there is that much more legwork to figure out what happened and how to fix it. You cannot possibly keep track of everything from everyone, unless you personally have the animals in your possession and you yourself are in charge. Guaranteeing animals that are coming from other people is a recipe for disaster, and I am afraid it will come back to bite you at some point.
Furthermore, individual pictures of the exact animals for sale are important to almost any serious collector or breeder. I can give you an example of my hunt for quality salmon hypo boas. They are my favorite boa morph, but there can be extreme variety- some have that deep, orange-red base color and nice mahogany saddles, but others have a lot of brown and dustiness to them, and still others are very pale orange and tan. I have 1.1 and they are two very different animals. I have also looked at probably close to 50 specimens before deciding on the two I got. Why? Because individual pattern and coloration can make or break a deal. I could never have known what I was getting had a ordered without first seeing. Likewise, there are potential problems, such as stumpy tails, nipped toes, spinal kinking, etc, and signs that an animal has not been kept properly such as stuck shed, retained or wrinkled eyecaps, dry scales, thinness or obesity, that as a buyer you cannot possibly know unless you see a picture of the exact animal you're ordering.
I hope for your sake you take our advice to heart and think about possibly reorganizing certain aspects of your business. Best of luck, but until you have actual pictures of animals in your personal possession that you are selling, you won't be getting my business.
