I was actually an IT intern at a billing service and we had several new servers come in. I was there early (by about 4 hours) before the other 3 IT people came in and simply set up a Linux server to try and show them that it worked great (instead of paying Microsoft for the server software).

Turns out after showing them they liked it and they are currently running the Linux servers. Windows machines are used throughout the company for the regular users, but Linux for their servers storing all the patient information files, user data, etc. After spending about 3 months as an intern I essentially taught the Microsoft certified staff enough to manage the servers well enough (it's really not all that hard) and they still have them running (roughly a year later).

Point is, you really don't need highly skilled technicians, none of them had used Linux before my internship, yet all of them still seem to run the servers fine. One REALLY nice thing is that their Linux servers go down far less, are quicker, and are actually more secure than their old Windows 2000 servers they were running.
