Mark designed this site himself and I built the responsive layout templates with the twitter bootstrap frame work.
The homepage has a banner area where Mark can publish testimonials or quotes with images. They are displayed randomly. Under the banner are four projects that display if Mark sets their status to 'Featured.'
We used an accordian style collapsing list to display his long list of clients by industry.
And dynamic relationships between testimonials and projects add the clients' voices to the project descritpions.
