I'm thinking you'd end up with a lot of expensive normals this way.... with vet bills for worming and treating other issues they may come in with, picky eating, etc. I'd also wonder about having to then re-sell the normals that you have cared for and treated. I would wager you'd loose money on this operation.

The guy that used to run major league reptiles (or was it major league ball pythons??) used to take on imported animals as possible dinkers. I know he did it with large numbers. But I'm not sure what he did with the many normals he got in. I know I'd see him post possible dinker animals / trios for sale from time to time. I'm thinking he dealt directly with the farm / people catching them and directly imported them.

There's also a guy on youtube (DM Exotics I think) that shows videos of farms in asia that he buys from. He goes on site to pick out animals. He sometimes talks about the paperwork and other things involved, so that might be useful for you if you are interested in this.
