Convert CSS XHTML Designs to WordPress Themes

I am looking for some pricing on converting existing CSS XHTML designs to WordPress Themes that are widget ready. I want to retain the original design look in the sidebar for either the standard WordPress navigation or widgets. If need be, I can convert the code to WordPress, but I am not very good at coding the css for the sidebar to support widgets. So, I would also be interested in a price to only make the sidebar support widgets while retaining the original design elements. Must be compatible for all newer browsers: IE 6, 7 and 8, Firefox 1.5, 2 and 3.5, Netscape and Opera. I would like to see samples of your prior WordPress coding. Thank you.
