Website for collections?

Hi! I am a student collections assistant in a small college gallery, we use catalog.it for our basic information. My boss is wanting us to implement a new system for visitors to access information easier. We have 9 large cases with 5 shelves each, all in one room. My boss is wanting a QR code to link to the entire case, then options to take you to information about each shelf and item. Currently, our catalog.it website is sorted by geography, and I don’t think she wants to change that. How could I achieve this? Website recommendations? Is the best option to reorganize our Catalog.it website? I’ve never built a website so I’m just looking for advice! Thanks in advance.
