Calling for Column Coders!

I'm currently using the Atahualpa theme and really love it (much thanks to Alex!), but I'd like to configure columns so that the layout looks like the picture below. Any coders out there that can help or that can point me to a theme with options to allow this?

Contact me via Twitter or at CrystalArcand (at) gmail (dot) com if you can help.

Thanks so much!
