Allow Directory Listings To Feature a Menu w/ Prices

I am looking to allow for every person who creates a directory listing to be able to set up a menu for themselves. Each menu item will have 5 different pricing points, so I essentially want for the information to Display on their listing details page as follows

Menu Item 1 | Price 1 | Price 2 | Price 3 | Price 4 | Price 5
Menu Item 2 | Price 1 | Price 2 | Price 3 | etc. etc. etc.

If the info were to be placed into a simple html table that would work.

We need for there to be an unlimited number of menus they can add, but we don’t want an endless list of text fields that must be left blank if they don’t want to add any more items. SO, we need for there to be an “Add Another Menu Item” button that allows them to keep adding until they are satisfied, or at least someway for them to reasonably list a large number of menu items.

I’ve tried various “menu” plugins but I need for it to be editable on the frontend, it also has to attach to their listing so that doesn’t seem to work.. I tried using the custom fields to edit the geodirectory listing creation page built into the plugin, but I was not able to control how they appeared when editing them OR on the actual listing page. I could really use some direction here, I’m basically banging my head against the wall at this point with Google searches for who knows what. It seems there are so many ways to do this I don’t know where to go next..Any easy options?
