add seo & product feed in opencart

Project Description: I have a site that is an opencart store. I want someone to give it 100% seo and then submit it to search engines everywhere. I also want someone to setup the product feed and then submit this to shopping sites everywhere. Targeting mainly UK customers. I understand that the best shopping sites charge (some blanket, some by cpc - I ask that you setup the account and I will provide / input bank details as and when is necessary). Also small promotion campaigns (blogs, facebook, twitter) required after the above has been done. I guess this could all be done in a 3-4 days (doing a 3-4 hours a day). The site sells cases for Apple Devices, Blackberrys, Samsung Phones, Tablets, PC's & Laptops.
