Need template/plugin to organize items

Sorry I can’t think of a better title to describe what I need. I am trying to create a website for an antique dealer. She wants to add select items to the site but this is NOT an e-commerce site.

How can I create an easy-to-use template or something that she can add and remove items. It must contain a picture, title, description and price. All inventory items will live on a single page. No need to create a different page for each item.

I’m hoping that there is a plugin that exists that does something like this. I am using the Covera theme by InkThemes.

Thanks.
Gary
