Numbering the SysAdmin's days (Score 1)

The sys admin will be around forever. But what I'm trying to do is estimate the major cost components that make up the sysamin's job. I'm a market researcher looking for any industry cost data on managing UNIX + Linux + NT server farms. My specific focus is software configuration management -- software distribution and application deployment. I'll use this data to create a cost model (spreadsheet) which I'm happy to send to anyone who wants the finished product ([e-mail]). In the interests of full disclosure, I'm doing this work on behalf of a client (a startup vendor). However, none of this will be used as the basis of spam or any sales activities. Thanks for any pointers / URLs
