shipping my snake

does anyone know how to safely ship a snake cross country/have any recommendations or tips?

this is a really hard post for me to make, but im moving and unfortunately im no longer able to keep my snakes. i know i can sell my ball python (if anyone is interested in a lesser), but my corn snake is an albino and i know she’ll never sell. fortunately i have an experienced reptile owner cousin who is willing to take care of her, but we live on opposite sides of the united states. i’ve never shipped a snake before and i plan on shipping her tank and all of her husbandry (separately ofc). she’s small and about 1.5-2 feet long.

im heartbroken so please be kind. i know this will be best for her.
