I'd rather do a short list well than a long list badly. Here's everything I take on, what it's for, and roughly how it gets priced.
Printers that drop off the network, computers that got slow, an update that broke something, email that stopped sending. The everyday work, same-day, remote or on-site.
Dead spots, dropped connections, and a closet full of unlabelled boxes. I plan the network for your building, run the cable, and hand you the documentation.
Cameras placed where they actually catch a face, recording long enough to matter, and set up so you can pull the footage yourself six months later.
Automatic off-site backup that I verify, at full quality with nothing left out. Restores are included. Month to month, sold on its own.
Three shapes, depending on the job.
What I don't do. I don't sell equipment you don't need, and I don't take on work I'd be learning on your time. If something is outside what I do well, I'll say so and point you at someone better.
Describe the problem and I'll tell you what it actually is. Most calls end with a plain answer, not a quote for something bigger.
