Simple shopping cart

I require a simple add items to cart. The site is hand built (not wordpress) and the database exists (prod codes/price/image etc etc). Functionality: From product list, user adds item to cart (cart icon/div simply updates quantity of items in a visible/animated manner) When user clicks cart - new page, lists all items (image, product codes, description, item price and total). In this page, each item quantities can be updated and items can be deleted (maybe via ajax, rather than resubmit). Upon submit (checkout) - the cart contents, in html format with images etc to be sent to webhost and the actual customer email addresses. The information is to be added also to a db table for future reference. No merchant processing is needed. Requirements: Shopping cart to be made in responsive manner (not tables etc). add to cart/change quantities to be styled in css, not standard dropdowns or submit buttons etc. *Project needs to be completed within the next 7 days.
