CSS Ninja wanted.

Hi, I need your help to pretty up fully functioning online calc UI (input fields, date picker, slider, result output etc.) and make them look really attractive, easy to use and clean looking - strong experience in CSS3 / Javascript / HTML5 / Wordpress is a MUST. Attached is an example of what I like - [login to view URL] (click on "calculate your bmi" button) To get this job, here's what you MUST answer below questions: 1) How will you create better than this example UI for a calculator on a wordpress site? 2) Example of your past online calc/CSS work examples. This can easily turn into a long term contract opportunity for someone with right skill sets. Thanks and happy bidding :)
