Thank you for your quick response.
I can code, I have no difficulty using CSS and XHTML. In the past I have converted PSD designs into quality websites however, I don’t have much experience using PHP and MYSQL.
After looking at the website I mentioned before I can see that the HTML and CSS doesn’t mention anything to do with wordpress. Creating similar packages as they have and setting up a CMS websites for a client would be more beneficial for both them and myself as I wouldn’t be hounded to do updates. I can modify and manage no problem, however unbranding the theme is something I would want to do to uphold a professional look.
So do you mean use plugins similar to this one below?

Also when moving the CSS files to different directories in my webspace wouldn’t this muck up the MYSQL database?
Many Thanks
