Matt:
Me personally? No. But I can see a small business going for it if it includes LAN, PC, Printer, and Fax support, repairs, maintenance, backups, and upgrades. If the company has a copier, they probably already have a pretty good relationship with their copier supplier.
The Geek Squad in Minneapolis is similar in concept, and they probably have a web site.
One interesting trend I have seen in many businesses is to discard and replace equipment at the first sign of trouble. This is because it costs less to replace it that to even do one service call on it. In fact, my current client discards ink jet printers rather than replacing the cartridges. I have done the same thing with all manner of computing equipment.
