Catalog Script

I need a little script to catalog. Backoffice: Create categories Create sub-categories Create products for categories / subcategories. The products you can upload an image and you can upload a pdf file. Site: On the site, will only be a page that will display the catalog. The categories are the menu to see the products in that category. The products appear all followed with the next image, if you have a pdf file, a button for uploading. Must have a php file with any language, in order to be able to make an easy translation when necessary. There is a script similar to what I want, which is this: restaurantmenuscript[.]com Similar to the level of backoffice and presentation of products on the site. This work is to be surrendered as soon as possible.
