How much of a bounty to get this onto an Android?

Intro video -- Monetas iPhone app:  https://www.dropbox.com/s/cotk860n3e49kpn/monetas_iPhone_intro_HD.mp4
This app does a lot more than you see in the video, which is meant to show basic functionality.
I'm recording an "advanced" video tonight and will post a link soon.
P.S. most of the code in this app is being re-used in the Android app as well as the "Holy Grail" project.
