PHP Script to create sample products in Prestashop

I need a php script to create a product on prestashop 1.6 starting a data stream like this code name description image producer attributes List Price Suggested retail price availability category I do not ask for the creation of a custom import, ask the realization of a script where passing data in variables I create the complete product of prestashop, for I intend to complete categoire and images using the native classes of prestashop to mapping and full of attributes (groups and associations) ----------- the script should be independent, should not be a module prestashop !! the script needs to create a product from scratch if the product does not exist on the site, if the product exists it jumps I do not want a full script that processes a csv, I want a script that creates a single basic product and just the script should verify that the product does not exist, if there is the jump if not it will be created the script has to create the tree categories if there is and must be mapped categories the script has to create the images produced and must be mapped the script has to create the attributes if there are no ---------------------- I Consider this to be a simple task for somebody who knows what he is doing. Please do not bid if you need more than 2 hours to get started or to understand any part of the job description. max price 100$
