Create Working Contact Form

We need a contact form on a website changed so that it will work on Windows Server 2008 (IIS7). We previously used a perl based script called formmail for the form but now need to redo the form to work on the Windows Server. The server runs iis7, mysql & php. The project is fairly simple as the form has already been designed and it is up to you to recode it to to work on the new server.
