Design for Joomla or Drupal website

I need a designer who can create a custom design for my consulting business. I will use either Joomly or Drupal, depending on your recommendation. It will initially a rater small website (3 pages), which will grow over the next few months to about 15 pages (more company, project information). The initial pages will be the homepage, about and contact, which we will fill with content and extend as time goes on. Your task will be to create the design for the "theme" that will be used for the site. Attached you can find the company logo. The company does business process consulting, automation and custom software development.
