I have a question regarding how much I should charge per computer repaired or maintained. Basically, I applied for a job doing basic work on PCs and the employer wants to know what I'd charge as a service fee per unit. I have never had to come up with numbers for that before, as I am payed hourly at my job now. So what would be a modest price per unit for fixes such as hdd formatting, installation of windows 8 (sigh), some software installs, and basic hardware diagnostics?
EDIT: If it means anything, there are 13 PCs that need to be done as far as I know.
