Hey there! I can definitely help you. I haven't had a baby sand boa in a while and it's been too long for me to have saved pictures of the setup, but they're basically like my adult enclosures but down sized. What I would do is get a ten gallon, fill it up with 4-6 inches of your choice substrate (something that holds a burrow preferably. I use dry eco earth but aspen shavings also worked), and stick a che on top. My hot spot is usually around 94-96 F and the ambient temperature is about 78-80. On top of the substrate, you don't need traditional hides but you want a lot of ground cover. I use hanging vines and cork flats effectively, although they're not shy about using the water bowls either. I'd advise against putting anything heavy in the enclosure unless it's secured in place and flush with the bottom since the heavier the object is, the more eager they tend to be about burrowing underneath it. They're really not difficult to maintain and can be rewarding specimens. Here's a picture of one of my adult setups:
