513277 Import module for Prestashop

I need an import module for prestashop that allows me to import the most used datafeed formats (CSV, XML, TXT) into a prestashop store and automate this thru a cron job so the import is done in an automatic way and not manually. This module for prestashop must be: -Multilingual (I work with datafeeds in several languages) -easy to use and set up. I'd like a file with instructions on how to use it easily. -Fast and clean, it must not load extremely the server when executing. -Cron job for automatic imports is a must. -The import module should allow the user to determine what fields in the datafeed corresponds with prestashop fileds and write the name for it in the corresponding language. -Functions: It must add new products from datafeed and then update the content that has changed and delete the content that does not appear in the CSV anymore, that is, the content that was once added but now it has been removed from the supplier's datafeed. -The import should allow the deletion of existing categories and products but only if the user selects that option. The content imported from the datafeed may be an addition to other products and categories added manually, one must not substitute the other. Please, bid only if you know very well Prestashop software, how it works and if you can provide a solid effective import script.
