What education and/or training do you have that relates to your work?
All the time. It is a 2nd job.
How did you get started doing this type of work?
By accident. I was a political science and languages major in college. I was working at Fidelity Brokerage (Investments) studying to become a stock broker and my boss (in 1984) said "We're going to get a personal computer and I want you to learn how to use it."
What types of customers have you worked with?
Training, networking (wireless usually), "cleaning up" the computer, giving advice about new equipment, setting things up, replacing/upgrading parts, general troubleshooting,
What advice would you give a customer looking to hire a provider in your area of work?
Find someone who you believe has your best interests at heart, not someone who is just in it to make money. Don't let anyone intimidate you.
What questions should customers think through before talking to professionals about their project?
I have been working with computers for 30 years and believe it or not, I do remember what it was like to feel like I had no clue about this thing that they call a computer. It is easier than you think it is and it keeps getting easier - or "user friendly".
