a more Nonprofit feeling theme

I am having trouble finding a theme that meets the following needs:

I want to have 2 or 3 separate content columns on each page (or at least the homepage). I also do not want the sidebars to show because I am not creating a blog, but instead a website for a nonprofit company.

Could anyone point out a particular theme or plugin that would be useful for me to achieve those requirements? Thank you in advance!
