I want someone who is an expert in Zen Cart, that can build some database upload utilities that will allow me to bulk upload products and / or categories to my Zen Cart store.
The category "trees" will be delimited by "~" symbol; and the tool needs to build all of the leaf categories, and make sure every branch is unique (no duplicates).
Again, you have to know the database inner workings of Zen Cart to make this work.
