What do you have in mind for the style and theme of the business card?
I really like the ideas I've seen here for tech companies. Many are very colorful, have things on both sides, incorporate rounded edges, and may use symbols for phone and email instead of the words "phone" and "email".
Some designs that I like on this site are the ones for Cloudline Solutions, Green Shoot Group, and the winning one for Umbrella Software.The Quest Consulting design is nice too.
You may want to recreate the logo to clean it up or resize it. It's just a serpentine bold font with the X in the middle.
Brand name to include on the business card
What to avoid
I don't care for the stodgy business consulting or recruitment firm styles I've seen here and on other sites. I do like the blue and green logo colors so try to keep those unless they are really posing a problem.
