Prestashop Auto Import Products

We have a Database of products that can automatically generate and up a zip file containing photos of products as well as XML file with product information. I need a script to handle and process the uploaded zip file. What the script will need to do. 1) Our POS will trigger the script and upload zip file via FTP 3) script will rename zip file to "date".zip 4) unzip file and place photos to images URL 5) Process the XML file so it can be imported to PrestaShop cart. - The XML won't have all information required, so the script will need to be smart enough to input image URL and map categories to the shopping cart category numbers and remap other fields as well. Fixed price for this job and milestones must be approved before payment made.
