Setting up a server for imaging using ghost and win server 2003

Hi,
Please bare with me as I am somewhat of a newbie.  I am starting a computer rental company that will be deploying anywhere from 5 to 50 computers out to clients at any given time.  I will be starting this at home and want to know the best way to set up a server for imaging.  I have a network setup already and will be putting the server after a dlink router (di-614+).  I will not need to access the server from my home computer but will be installing a 24port switch from the router for the server and computers to be imaged.  I will also be using a KVM switch to easily switch from one computer to the next.  Is win server 2003 the correct software I need for this setup? Do I need Ghost corporate? Is there a anything else I will need?  Basically what I want to do is create an image copy it to the server and the copy it to the x number of machine to be imaged.  Thank you for your responses!
