We have an ongoing contract with Christo IT Services. They are courteous and professional, and their response and resolution time is PHENOMENAL. They are just great people to work with. They remodeled our entire computer system in 2012 when I first worked with them, and it couldn't have gone more smoothly. Most recently my printer died, and they contacted Dell (who I still had the warranty with), and I did not have to jump through any hoops. The next day I had a replacement printer.
