We gave them a challenging task, to create 'excerpts' of a web app that doesn't exist yet which could be featured as marketing graphics on a home page. They did a great job creating the desired excerpts, and ended up providing a much cleaner version of the home page we sent them, even though that was not part of the original request. Really nice visual design, easy to work with, fast turnaround on revisions. Great use of colors, fonts, whitespace, etc, to create a professional appearance. Highly recommended!
