Advanced Ajax Category Tree with Configuration for Prestashop

Hello, I would like an advanced jQuery/ajax category tree with configuration for Prestashop 1.5 and compatible with Prestashop 1.4. The goal is to display a category tree and to associate a configuration to each category by using a recursive function.. The program will be statically callable, and also ajax callable to dynamically refresh or display the configuration. Only the modified items would be reloaded. It won't have any depth limit for the categories, everything should be recursive.. Here is attached a PDF file which contains our wishes and explanations. When your program will be written and you will think it's clear ; you will have to rewrite it shortest and clearest ! We would like also the respect of Prestashop coding standards. We will put it through the validator. We want only jQuery specialist, you must be very experimented and strongly skilled and bring to us your references or samples. Developper Profile : OOP PHP5 Expert, jQuery Expert, recursives functions skilled. The approx budget is $500. It will be splitted in millestone. On first milestone, we would like to have a code preview to decide to stop or continue. If we decide to stop, you will be compensated by the amount of the initial milestone and the project will be deleted and reposted. No form letter. No company presentation. No fake, not bots please. Please give me the sum of 12 + 4 for flood and spam control. Thanks for your bid.
