This guy does it all: he fixes computers, sells parts, networks.....everything you would need an IT guy to do for your business. He's an outside contractor, so he can come to your office or you can bring him your computer to his shop on Military.
The only thing you should know: he's geared towards the professional user, not the personal (home) user. But if you don't have tech. support on your computer anymore and can't figure it out on your own, this guy can fix it for you.
