Wow Jon, that is an excellent breakdown, that staff salary looks kind of cheap though, you hiring straight out of college?
I think the one thing that could possibly jack that price up though is the space, not to may cities offer facilites that wouldn't require a lot of work in making it ready for a Data center. I worked for MCI in the early late 80's early 90's for a few years and I learned so much from that company as far as networks and datacenters, but they made the same fatal mistake most companies that get that large do, they start scrimping at the employee level and then things go downhill from there. Funding abuse by upper level management always has to come from somewhere though.
My point is I think you could do a great job of running a DC, maybe we will see you doing that soon.
