I've helped a lot of local first-time snake owner customers get their setups correct before I send a snake home with them. If you have local breeders available, reach out to them for help. Most are glad to, especially since they know a baby they produced will go to a good home.
Also state that you're looking specifically for a pet rather than a high-end morph so the breeder can steer you to a baby that tolerates handling well.
