How long does it take to write something like bambooinvoice?

I agree on this one ... I dont think you could guess at how long it took to create, I mean I was working on Dove Forums (www.doveforums.com) for nearly a year, and work is still ongoing.

As Loic says, your best bet would be to try make your own version as this will really help your learning curve.
