What types of customers have you worked with?
My most common jobs are: removing viruses, repairing windows, and restoring precious photos and documents that a virus or windows breakdown has made it impossible for my client to get to. I love exceeding my clients expectations so I get rave reviews to everyone they refer me too.
What advice would you give a customer looking to hire a provider in your area of work?
Beware providers quoting an unbelievably low price. Either they don't plan to take the time to do a complete job, or they plan to bait you with a lowball price then nickle and dime you with surprise charges. If they can't give you a range of best case, worst case charges, hang up and call me. I can usually guestimate not only what's probably wrong from what you tell me on the phone, but also what the labor and parts are likely to cost. You might not like the truth, but its better than some shops that lie on the low side then demand super high prices once your machine is torn apart on the bench, or even worse they didn't even finish repairing, so they can act surprised when you have to bring it back. I tell you the truth, charge reasonable prices that I quote you up front, and get your computer running great again :)
What questions should customers think through before talking to professionals about their project?
Computer repair is full of rip off artists. If they don't have licenses or any address, find someone who does. And of course, if it sounds too good to be true, be suspicious.
