Simple Newsagent Management Site

Looking for a very simple website that enables newsagents to: Create an account (Company Name, Contact Details, Etc) Create an ongoing order of newspapers (They can select the number of newspapers they want delivered). They also need to be able to select a date from a calendar and nominate how many copies they sold. Our newspaper comes out twice a week (Wednesday and Saturday). Most newsagents take 100-500 copies. They need to be able to change this number whenever they want, but also record how many they sold for a particular date. Very simple! Need loaded onto our webserver and we will supply our logo to be included on the pages.
