That always amuses me when people say that about something they are doing on their own time.
OK. How much it would cost ME to hire YOU to format drive, install W8 and its 96 updates, then update W8 to W 8.1 and last not least install and configure some 20 software apps.
That's how much this is worth.
I did it on my own time, but not for my own pleasure. I did it because of the buggy 8.1 update that can not install itself.
