The main audience are webmaster and website owner, and also potential buyers.
The logo name is "pagetrader" you might also create two version, one with "pagetrader" and one with "pagetrader.de" and a sloagn "Kaufen und Verkaufen Sie Webprojekte", righ now we are not sure about the color, so we are up for all entries! What we need is the Illustrator file, so we can change the logo if we need to.
Here a few websites from the U.S where the idea is already used, so you understand what we exactly do.
A web 2.0 style would be great too!
A Logo Signet is also great!
