What do you have in mind for the style and theme of the business card?
I believe architecture is ART so my business cards need to match this philosophy. I like clean looking cards yet it still needs to scream "design" and "art" at the same time. The typography needs to be simple and modern.
Not sure what it would look like (or if we want it) but we are not opposed at this point to including some type of blueprint (house plans) to the card....just an idea.
Use Red, Blue, Greens, etc for my logo. whatever you think looks best.
