One of my managers at work asked me if I could fix his computer for him. He said he wants it factory reset, and updated to Windows 10, but he wants his nearly 30GB of music backed up. He also wants a new battery. So, for the new windows key ($100), the flash drive to backup and transfer his music (~$15), and the battery (~$20-$30), that's $150 out of my pocket. How much do you think I should charge for labor?
