Developer / Themer / Desiner

Hi there - first post - been playing with drupal for about 2 years.
I have developed a site using only free theme. Now I am at a stage where I need a very professional look.
I am looking for an experienced Themer who can translate a design into an existing drupal frame work.
Tasks would be to theme: calendar, panels, display suite...
Does anybody know an advanced Themer? Or can direct me to someone with examples of their work.
I was thinking of getting a designer and the Themer to work together in a Team.

cheers
