Good news here. One of the forum folks here is an art director with a great looking portfolio. She'll be having a crack at logo design. Also, on general card look (which has a technical problem that we're trying to see if we can get around*).
*This being that having special "backgrounds" is problematic. The website pieces the cards via CSS positioning, so that you can look at the card on the web (looks nice), as well as print dynamically at highres. However, if you position images on top of each other, there's issues with the printing side of things. This, we've determined, we can get around by pdf generation scripts, but then that creates a much larger server strain, which could be problematic if the project gets really popular. Anyway, because of all of this, we're looking into a card "border" as oppose to a background (at least initially).
