Fixing of Prestashop ixtheme issues

Hi there, Here are the changes summarised that i would like to get done to my website using Prestashop and with theme ixthemes / ixtengine). We have a theme installed from ixthemes and which we need to customize for the following 3 areas: 1) The theme header/pre-aheader is unconventional. We want the header of our theme revised to make it a compact presentation like what is seen on sites like firstcry or ikenstore and other ecommerce sites in general. The attached design doc has included how we would like the header to be. 2) For some reason the add to Cart function has stopped working.. not sure what happened but I remember that adding to cart used to work smoothly. So need this defect fixed. 3) The theme/widgets that came ixtheme theme has limitation on re-use. Couple of widgets which are currently used by the site donot allow us to use it multiple times on the home page. We want the widgets code duplicated such that these 2 widgets can be used multiple times using code duplication or so. The current limitation with the widget is that it is restricted to only one instance use. Basically, we want the widget duplicated such that we can have IXT511 or IXT512 and so on multiple instances which can all work parallel. The engaged developer should be able to document and show the duplication of widget process to use so that we can internalise it. 4) The enhancement should not break the EXTengine workings as this is the one which is used to configure the front end of the store/the theme. We think this is no more than 1 week of effort at the most and so expect quotes accordingly. regards, parag
