Gartner reports

I am a helpdesk technician. Our organization has 1900 users and only 2 helpdesk staff. I am trying to convince my CIO and the director that we need at least 4 helpdesk staff to support 1900 users.

Does any one have recent Gartner reports ? I know it cost almost 1k , which I don?t have. But I would appreciate if any one have any recent Gartner reports. my email address is boppi1@yahoo.com
