Bygg en hemsida

I would like to have a .net builded website with API, easy to integrate and connect with other shops for fast delivery. The site should have 4 different profiles 1. Seller 2. Transporter 3. Service Point 4. Admin Every profile should be able to see statistics and add comments along the way the transport sale is being done. I need the site to be finished till 23/9-2014 and my visitors should be able to track their order with a unique key ( number id ). The track system should be by GPS from smartphones and the keys would be attached to the transporters phone gps. Its a little complex but it's doable. More info on chatconf.
