What types of customers have you worked with?
At the top of the list is slow computers. Next is problems with viruses, weird ads popping up or your browser going to pages you didn't click on. Then error messages like a "DLL" is missing, or a program won't start. From there on it really gets into mixed bag - lost internet connection, mouse stops working, can't connect to wireless, email doesn't work when traveling, etc. Also there are requests for help where there is no problem: Set up wifi, install programs, install a printer, even "how can I get pictures off my camera." It's what makes our job so fun, the possibilities are endless!
What advice would you give a customer looking to hire a provider in your area of work?
Look closely at experience and professionalism. Computers and software are extremely precise, working with them at a high level takes a certain type of person - exacting, detailed, sharp. Avoid know-it-alls, they're forming ideas before you explain the problem fully. You want a very good listener, and also a person that speaks in plain english. Someone talking in geek speak is either trying to be impressive doesn't have good communication skills.
