37168 very simple order system

What I need is a very basic order system for my existing website [login to view URL] This is a German webiste where I sell only a very limited amount of pullovers etc. Just have a quick look. I currently use a php send form which sends me the orders to my E-Mail adress. This is not a very good solution. DETAILS: Customer can choose item on the "Bestellen" (=ORDER) page and can choose shipping and payment cost. TOTAL is automaticly calculated. When customer doen't fill out all required forms, he cannot proceed. When he sends the order, it goes to my MySQL (or equivalent) database and I need a backend where I can 1. see all orders 2. can select order as paied for (checkbox), can select order as shipped (checkbox) and can make comments for the order. The system should send an E-mail automaticlly to the customer once he sent the order! An E-mail saying: "Thanks for your oder" etc. And should also be able to send pre-defined emails with variables like customer name, product her ordered, from the backend. So, what you need to do is create the MySQL Database and tables and so on and then write some php code for the order form as well as for the "backend". I tried to do it myself but I don't have enough time to do it. If you have any questions, please contact me.
