I'm not sure where you live, but you can look into various rescues/shelters in and near your town as well as actual local reptile groups to meet breeders. Depending on how serious you are, you can even look into different reptile conventions/shows. And then.. there's always your local Petco store.. each store is different, but many of them carry a plethora of reptiles. Good luck!
unfortunately in my country there no rescues/shelters, local reptile groups
actually in kind of pet reptile isn't available in my country I have contact to a pet exporter last month but his prices are so high Like ( 300$ for baby vield chameleon ) Its hard to get a unique pet on reasonable price in my country.
BTW I am living in Pakistan ..
