2 Prestashop plugins : Rollover image & Order method by sales - open to bidding

Hi, Please find below more informations about these 2 plugins : Rollover image The goal is to create a plugin for a rollover effect when users put their mouse over a product into the product list. The merchant has to be able to choose which image he wants to select for the rollover effect. So when he’s editing a product page, he will be able to select both cover image and rollover image. Order method by sales You have to created a new kind of order method based on the number of sales per product. If we select this order method and descending default order method, the product with the biggest number of sales will be display in first and so on with descending order. If products have been sold the same number of time, products have to be ordered by "product add date", from the newest to the oldest one. This new method of order will appear in the pagination block (Preferences > Products) into the "default order by » selector.
