Where in Oklahoma are you?

One or two thoughts -

There are somewhat frequent shows in Tulsa (actually Broken Arrow), OKC, and Dallas/Ft. Worth (Arlington). The OKC and Arlington shows are owned at least in part by a feeder supplier (Pet Snake Snacks), and he may not be willing to allow a competing feeder supplier into his shows. (I don't know that, just speculating) I've also seen him at the Broken Arrow shows. Otis is a super nice guy, though. You might want to talk to him. There are a couple of LARGE scale reptile breeders in OKC. I don't know where they get their feeders though.

You're gonna have to sell a LOT of rodents to make a living at it. I think in order to do that, you'll need to find some clients that are willing to buy from you exclusively (large scale) or go mail order with frozen. If you go mail order, competition may be stiff. There are a number of big rodent suppliers out there that have a pretty faithful following.

Also keep in mind that Big Cheese is in the Dallas/Ft Worth area and considered to be a high quality feeder supplier.

So, do your research. Talk to large and mid scale reptile breeders about potentially being their exclusive supplier. Find out if you even CAN get into the local shows. Good luck!
