Let us begin by studying how different background colors look against the "blue circles" logos.
The following can be used simply as a reference, or could be one side of the business card.
 
 
 
 
 
 
 
 
 
 
 
 

This one works well, but it cannot be written on, since it is rather dark.
 
 
 
 
 
 
 
 
 
 
 
 

This coloration could vary depending on the type of standard cardstock available.
 
 
 
 
 
 
 
 
 
 
 
 
 
 

The plain white one, actually isn't bad, and would probably be cheaper!

Four coloration schemes for a pretty basic, but nice, clean and professional looking card.  The backside would probably remain empty.  I like these...actually I like all four colors!   White is pure, more sterile.  Dark grey is more aggressive, avant garde, Yellow is a bit more friendly, with a bit more emotion to it, light grey is less agressive than dark.

Here are two, slightly more creative ideas.  These could be printed on a white card. I think I like the second one best.

These may need some work. I was working on a jovial, friendly looking design. Not sure if it's quite there!
 

Just for kicks, here's a fresh logo idea.  I kinda like it too!

Finally, an example of a "post-it" note that could be developed on standard color notepads.  This could be one of the most useful places for the logo!
