How to Buy Ghost

I want to purchase Ghost 15.0 to create a master image that will be installed on 8000 computers across my company. How is Ghost licensed for something like this? Do I need one copy for each of the 8000 computers or just one copy for the computer where I create the image? I can't find any info on norton.com about making a purchase like this. Does anyone know an approximate price? Furthermore my computers are all Dell computers. I am a Dell image builder customer. Dell ships me ghost images from image builder. Is the license required to install that image part of my Dell image builder purchase or am I responsilbe for buying the Ghost license needed to install that image? This is the same image that Dell is installing prior to shipping my computers to me.
