I am looking for someone to help me create a theme for my high school.

I've made a site that we all like the look of, but it requires reasonable knowledge of XHTML and PHP to use, and I'm the only one at my high school who has even heard of those things. So, I've decided to use Drupal as an easy-to-use CMS for my school to use after I graduate. You can see a screenshot of the design we like here. If anyone can help me make a theme for Drupal 4.5.2, I would really appreciate it! Thanks!
