e-commerce WEBSITE DESIGN

We want to be able to host this on any computer.. I need a very custom job to build a website for a online clothing store. I have had one previously completed but they used a simple template system. My new website needs to be custom made. I have attached some design concepts. I have a graphic artist who works for me who can do the graphic part of it however I need someone who is extremely clever to complete the back end of the site. I look forward to hearing from you. This type of job would require a lot of programming that we do not do here. We need to be able to modify this website ourselves. E.g add a new t-shirt design in etc. Merchant Ecommerce Website Shopping Cart Facility content webpages ‣ maximum products ‣ Unlimited product photos ‣ Content management system ‣ Up to 10 images / photos for non-product pages ‣ 1x contact form ‣ ‣ Working with provided designs to translate to website code ‣ DPS and Paypal credit card processing ‣ Shipping system included ‣ Manual stock control system, i.e. tick a box if out of stock ‣ One product attribute, e.g. size or colour ‣ Customer order history stored, and emailed ‣ Google Analytics website statistics ‣ Standard browser support (IE7-8, Firefox3, Safari3-4) Extra attribute per product Private login for designers Designers-only area Customised shopping cart process Extra credit card processing option (PayPal) Countdown and featured product management Special offer countdown timer: Visible on the homepage for visitors to see the current featured t-shirt and a clock to indicate length of remaining time for offer.
