cleanup CSS on Wordpress site

I'm looking to hire someone for a quick and simple fix to my website - [login to view URL] On the main page, the big green "search for homes that are..." box has a small issue that I can't find. The box "located in" seems to start off smaller and resize to the current size. PLUS, the placeholder (onfocus, onblur) disappears in IE after the text box is clicked on, where the other text boxes work correctly. Obviously you must know css and Wordpress, but also knowing Thesis is highly recommended. This should be an easy job for someone, I just can't figure it out myself.
