Prestashop module modifications and improvments

Hello, I need to modify a module that I have bought on Prestashop Addons. I also need to add various functions to this module. The module I need is based on the BulkOrders module (here on Addons: [login to view URL]). Youy can discover the module from the demo site links. Jobs: - Hide few columns. - Add few columns (Address comment, Country, full address display in a textarea form field etc.) - Add a icon to show up the shipping address in a tooltip. - Add a icon to show up the order message thread in a tooltip. - Add few simple options in the "Bulk actions" button. - Generate a PDF file. This PDF will be divided in columns and row. In each cell must appear the shipping address of each one of the selected orders. This is in fact a PDF sheet to print our shipping labels. So you will have to make the TPL from which the PDF will be generated, using PS native functions to make PDF from TPL files. Compatibility: PS 1.6.1.6, multilanguage, multishop PLEASE DO NOT BID IF YOU ARE NOT PRESTASHOP 1.6 EXPERT !!!
