Looking for customized skin to match existing site

I'm working on a site and I'd like for someone to create a skin to match the rest of the site.
Here is a link to the site on our testing server:
http://www.ellejaysproductions.com/tessa/index.html

I will be replacing the image-based nav with CSS in the near future. In this page the black boxes represent the thumbnails. I can provide you with the CSS for the nav, when it is complete.

I am willing to pay 15-20/hr. If your rates are higher, let me know and I will consider paying more with some proof of work completed and/or references.

As far as time frame, I am flexible. I'd like to have it done by the middle of May.

Thanks in advance for any serious responses.
