Build Ecommerce solution with marketing plan for UK and payment gateway integration

The job is to create the online aspect of a food label selling mainly our own lamb and beef via the internet. We would need a front end design, and also back end modules built. logo creation, everything really and hopefully all by one company so as to ease integration and completion of the project. The site would require the following ( in my non expert opinion, so if you have any alternatives or i am missing something please let me know ) 1) Front end design, A welcome page, with perhaps special products on the home page & logo 2) Outward facing shopping cart, where products are displayed, photo, description, price and add to shopping cart, cart must have boxes to put in discount codes to allow % discounts to first time buyers, and hopefully affiliate marketing codes 3) Blog section where content can be created to give the google bots something to read and hopefully add quality to the page ranking and therefore improve the SEO, here we could include articles such as recipes, infomation about the way the lamb, beef or whatever is being sold is raised and such like 4)Back end Admin module allowing for the products avaliable and general content of the site to be changed without programming skills. Hopefully be able to manage stock via this panel also so as to not need to contact customers to tell them out of stock 5) Customer Module, - Allowing the customer to create and account where they can see their orders, see their historical purchases, store addreses etc etc, the ability for subscription to monthly/weekly or what have you packs 6) Mobile friendly, this is vital, i would imagine more traffic would come from tablets, cell phones and the likes than a computer, so it must be tidy and bug free in all the most common screen sizes. 7) Mass Mailing program such a mail chimp integration 8) Payment Gateway integration 9) Plan for general SEO and clever positioning of the Key Words to make the PPC marketing as cheap as possible. I hope this is a clear enough explanation of what we require, Any questions please dont hesitate to ask and i will get back to you as soon as possible, we could also either chat on the phone or via gchat Some example sites could be the following (general site layout, not specifically the design, just the skeleton) [login to view URL] [login to view URL] [login to view URL] Thanks
