There are two sites on-line that I visit on a regular basis for hand-made items. The first is Artfire.com and the second is Etsy.com.
Both of these sites are on-line craft stores for creative and crafty individuals. I've seen some wonderful cards and printing examples on both sites. Look around and use the site search engine to narrow down your search. I'm sure you'll find someone that has the creativity that you're looking for.
