Looking at what you have posted on your site, it seems to me that you could use the Web Links module. Correct me if I'm wrong, but Description + Link = Web Links Module.
You could easily assign group permissions in the admin section to allow for whatever user group you wanted to be able to edit the information. You would also have the added functionality of being able to include a Screenshot of the site, if you wanted.
Maybe I mistook what you wanted to accomplish. If so, I apologise.
