Do a search in the DIY forum to see some of the homemade racks people here have built. They can be really quite beautiful, and great display tanks. It seems like you mean well, but you really need to do some research on corns. Especially if you want to get the closest to what's "natural" for them.
I agree with Jessicat on that. I think she means well but she doesn't have a full understanding of the needs a captive cornsnake has, as well as what they don't need.
I think that it'd be best for her to read up and get some information on different types of setups, heating and lighting, etc. But, if she chooses not to do that, there's not much we can do besides hope that someday she'll take the time to understand.
