It should have the basics of an e-store e.g. home page, product page, account page. On all the pages, except the log-in page, there should be boxes to display advertisements. At the lower end of the screen, ads should be able to scroll from right to left. Make the layout of the site similar to Amazon's, but with the ability to display ads like Facebook. Build it with any color, but blue must be dominant. Position the home account and cart links at the top and the service, about us and contact links at the bottom of the pages.
