What types of customers have you worked with?
Networking, fix printer issues, clean viruses and spyware, install software, replace faulty hardware, install updates, and backup files.
What advice would you give a customer looking to hire a provider in your area of work?
Look for companies with experience and good recommendations. Whenever possible, speak with the technician before hiring him or her to assess whether they seem confident they can do the job required and don't settle for the lowest bidder. Good service, proficiency, and experience will cost you a little more but will save you more in the long run.
