Website Project Goods Delivery

We need to develop a website where visitors can oder and buy simple deliverable goods. Imagine, as a mere example, something like a website where you can order food from takeaway restaurants in your city. We have two types of membership: the first one is for restaurants and the other is for visitors. A restaurant owner becomes an affiliate and has got a control panel for its online menu. He specifies the restaurant location via a Google Maps interface and adds his menu items with a photo (small thumb), a brief description and the price. Eventually some discount, and promotional features would be considered. The visitor will be able to search for a restaurant nearby, via the same Google Maps interface, and have all the restaurants listed based on xyz mt. prximity from a defined location, or he can simply browse for city, district and neighborhood. He picks up some food he likes and registers to the website in order to check out. At first the payment method will be paypal. After the order has been placed the system sends an email to the restaurant with the user informations and the order details. For what concerns the administrative interface, it should have three levels: administrator (website staff), restaurant owner and user. Try to imagine and fulfill all the useful features. The system needs to have some basic cms features, like webpage and menu management, and a banner management system. The graphic project must respond to high-standard requirements (see links below). Here is a list of websites where the idea has already been developed: [login to view URL] [login to view URL] [login to view URL]
