Any recommended themes geared toward ad banners?

Hi Fellas and Gals-
Are there any wpmu themes that support heavy banner advertising? I have a nee site, http://girlygirldirectory.com. After months of problemos with the directory plugin, I am finally functioning, but just barely.

I would really LOVE to have plenty of room to place banner ads all over the site, but especially the front page along the sides. The ads are just urls with an image. Plain and simple.

See these site for example:
