Ionut Neagu reviews the redesign of Themeisle, including the pros and cons of the decisions that went into it. The design itself cost $10,000-$15,000. Commenting on that Ionut writes:
While the design itself is something almost impossible to track the ROI of, I believe that it’s worth the investment. Frankly, considering that it took us five years before deciding to redesign the site, the cost only represents less than 0.5% of the revenues.
