I'm a 1-man IT, phone, and security department for 5 centers and growing.
Save your bread. If you really think you need help with your resume, I'll help you out. Failing that, see if you can get two or three of the more reliable (read: obviously sane and erudite) users on ToledoTalk to look at it and give you a few ideas. Don't be surprised if they come back with very few changes.
Off the top of my head, I'd suggest Maggie Thurber, Holland, HistoryMike, McCaskey, SensorG, Viola, OldHomeTown, Jimavolt and JR. All these people can write and I think all of them have been in management, so they've had to do the hiring. Make sure you include a cover letter along with the resume that they can see and critique. You might also include a reason that you're leaving your current company. And not because the boss is a real dick with the IQ of a fencepost.
Frankly, the sentence I quoted at the top of this post is enough to make me give you an interview. You've been dealing with five centers, hence five crews and their various quirks, demands and idiosyncrasies, which is enough to put you on the short list.
