Build a Website

Hello, I HAVE MY BACKUP of my old Oscommerce website that is at osc 2.0 MS2.2 - I need USE SAME CUSTOMER DATA for the new PRESTASHOP. This means that you would have to have extensive knowledge in Oscommerce and PRESTASHOP and in PHP/SQL to do this task. In doing this task I would need to have all current info (customers, orders and order history, password) from the old data base to be incorporated into this new data base. I have to make sure that once the site is upgraded that everything will run and that it will function properly. In new shop, prestashop 1.6, need to have the following functions/features to be working; 1) Sending customers emails for order status update, welcome 2) Registration – cc admin 3) Tax + price will show only at last step of checkout 4) Shipping + price will show only at last step of checkout 5) Create a html page that can handle with adsense and GOOGLE SEARCH CODE (check this page – will give you page url upon request so I know you are reading this description) 6) SETUP SKRILL PAYMENT 7) Product can be rearrange reorganizer by drag or position number change in HOMEPAGE and in CATEGORY 8) fix price specifics – when using currency discount price showing not accurate. 9) chat - free 10) REGISTRATION - country has to be moved on top and DOB has to go. 11) some adjustments to site. Note all ajustemnts must auto adapt if ever we change template or update version. Also, need to send me full areas/location of where changes is made in case for future changes. 12) check site for needed adjustment to make it fast. - Please note that this site is an active online. As for design I would like you being the expert might have nice ideas that I would con sider - in which case if I should accept your ideas and you do the work.
