The portfolio you're looking at is the portfolio of the person doing your project. Your project will not be handled by a junior designer or an art director who's been out of the design loop for ten years.
The same person will design and code your website: this is not only more efficient, but the comp you're seeing is really what you'll get. You aren't going through a sales person; instead, you're talking directly to a partner.
Graphic design shouldn't all look the same. We're focused on thinking outside the box. We work for clients who have original ideas and a passion for what they do; this sort of ambition has to stand out in the crowd, waving wildly.
