Time to bring this topic back to life...I have some questions.

What typically do you guys charge for each of the following:

(1) Diagnostic
(2) Clean system of viruses and malware
(4) New OS installation
(5) OS reinstallation/repair
(6) System upgrade (parts provided)

And how does the following affect your pricing:

(1) Go to their location to work or pick up machine
(2) Take their machine with you to your home/lab

Do you charge labor hours alternatively/additionally? If so, how and how much/hour?
