I have to say a basic reload of windows is 3 hours @30.00
I wont do that job at their place as its just too iffy and frankly 3
hours is whats chargeable. If you can save the data favorites/documents/music/wab and setting and reload with all software and updates and be done in 3 hours you are unbelievably good. Charge wise it is 3 hours but time wise it is usually at least 4 to 5 . Data copying and such is one on my specialties. It sets me apart from the usual suspects in computer stores. They cannot take the time. So I have created a niche market and believe me costs are not a question. I keep it reasonable.
Its their data and reliability that are the 2 greatest needed seconded by info on backup systems that are automatic like usb hard drives and ghost.
