CSS Site + CMS

I am looking for a very simple and easily administrated CSS web design that I can also have a members area and business directory. I would be willing to look at pre-packaged scripts. I also want a place for ad management for banners, google ads etc. If it is a CMS system, I want an easy one. I repeat easy one!!!! I will not consider any of the following open source applications: Joomla-Drupal-Xoops-Mambo etc. They are far to hard to administer. I am looking for easy. I like CSS designs as they are easily edited for colors, fonts etc. I would like a nice header with a design of a vegetable market or farmers market etc. I would like the have an RSS utility in place so that I can submit the feed to search engines for SEO. I do not want a blog. I am open to any ideas The project has to be very reasonably priced, that is why I would look at pre-made scripts that can simply be customized.
