If your payroll company needs a building, you'd probably hire a builder. If you don't know where to start on developing something as critical as a payroll system, I'd suggest that you engage a professional developer... Or have a search for "Open Source Payroll Software" and see if anything grabs your fancy.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
