c# project - web form

I have a simple web form application I would like done in C# 2008. The small web form application does the following. 1. Based upon a customer id the system will query a database and pull all items for that customer. Usually about 10-50 items. In the table the items include item id, description, price. 2. This is an order form so we want the user to select the items from the query in #1 and enter qty ordered for each item. This should be done on the data grid containing the items. 3. Once the user enters the order qty's an order is created which entails writing out a record in the sales order header file and the detail records in the sales order detail file. 4. We will give you access to a database for test purposes to pull information from. 5. The first screen on the form will be where the customer enters in a customer code and password. Upon validation by the program, #1 query will populate the datagrid. Then step 2 and so on.
