If you have a Mac or a PC that isn't working, isn't turning on, is running slowly, needs a cleanup, needs a new hard drive, display, etc, I can fix it professionally much cheaper than stores and offer a full warranty.
Also have experience with setting up office networking solutions, file sharing, remote access, etc.
I also do in-home training or things like setting up a television or internet/wi-fi or other network setup.
Could also help with iPhones and iPads, set up printers, anything like that.
Can repair cracked iPhone screens much cheaper than the mall or Apple store.
