Fixing Webbugs and modifying webpage

Modifying Website Hello, we need a PHP programmer to do some modifications to our prestashop. Tasks to be done: - Fixing the payment gateway from 5 step check out to 1 step check out and vice versa (at the moment 5 step check out is enabled. By enabling 1 step check out boxes jumping around). The payment site also needs to be redesigned etc. to make it better looking. At the moment is has pretty much the original outlook what comes with prestashop. - Homepage has to be redesigned and modified (creating new CMS pages) so user are able to change content on sites. Also changes to footer, site menu, and general changes needed on the homepage. (Old coding what not be used from preinstalled modules should be taken out because of loading time). Newsletter should be taken out from homepage and move to download page. - Adding new categories into the menu and creating cms pages for that category. User must be able to add and change content by himself for all pages. Linking up the content and helping out where to place links e.g. - Add module: On our website we have a Facebook LIKE counter already. On one site we offer free downloads. At the moment there is only one option to receive the download link. The customer has to inserts their mail address so he/she will receive a download link automatically. We want to add a module on that download site (second option to receive download link); what gives our webpage AUTOMATICALLY a Facebook like when a customer uses that module. After using that module, the download link must be sent automatically to the customer (Not sure what the module is called). - Add “Print this page”button on some pages (module is already installed and working). - Additional adding “Pin It” module, not sure about that at the moment, but like to mention it before. - Changing the Magic Zoom Plus function for one category how to view a product, changing from viewing “zoom in picture” to viewing “zoom beside the picture”. - Changing the host and make sure that all files and databanks got transferred so the website functions the same as on the old host. If problems occur they must be fixed.
