My suggestion would be Tech Republic. They have a lot of white papers, and might have what you are looking for. There are some white papers out there that have cost benefit analysis, but for a high school it may be a bit tougher because you can't readily apply a direct labor cost to the analysis. However, it may not be an issue in your case. One of the white papers I have read is called: Transforming the Customer Service with the Smart Help Desk covers a lot of this. Good luck.
