Design, layout, UI

I am planning to build a wordpress site based on the idea of http://votesmart.org
I need a design for the home page that incorporate the county colors (red, yellow, green) and the map (republic of guinea)and I have an issue the image for the logo that need to be recreated with transparent background. I will be using the same idea as http://votesmart.org ( same links and pages) but need no copy cat design.
