Unless a common webhost can demonstrate that they already have success installing and serving Koha, I would not believe them when they say they can do it. It's a lot more than just CGI scripts.
You are better getting a full server VM and doing installation yourself.

Mr. Yan Han,
I am trying to help out my kids K-8 school by setting up Koha on a Shared Host (namely 1&1). Thus far I have been unsuccessful. Can you please tell me if you ever had any success with your trials?
Thank you,
