Logo for Web 2.0 Site

My company provides web-based software to allow users to interactively decorate a room online using a drag and drop interface. Logo needs to emphasize the fun, interactive, and web 2.0 based approach.

DoodleSystems

Desired Color Scheme:
Vibrant colors (2-3 colors)

Desired Style:
Modern, vibrant logo incorporating "Doodle" and representing a fun and interactive web 2.0 room decor experience.

Accepted File Formats:
vector & bitmap

My company, DoodleSystems, creates software for a novel, interactive e-commerce site which lets users decorate rooms from the available products via drag & drop. DoodleSystems has several sites, including DormDoodle and OfficeDoodle. As such, I would like the main logo to work for the sub websites as well with minimal change.

What is common to each site I will be creating is obviously the "Doodle" part of their names, so I think for a logo to work consistently throughout my brands, the main logo should include "Doodle" and a graphic that is generic or abstract enough that it is valid for the sub websites. The font and graphic should portray fun and interactivity. It can be abstract or represent a piece of decor.

I do not have a color scheme in mind yet, but bright, vibrant colors are preferred. 2-3 colors would be good.

So to sum up, I'm looking for a main logo for DoodleSystems that includes "Doodle" as a part of the logo representing a fun/interactive/web2.0 manner. As part of the bid, I would also like a font that will allow me to add the different sites in front of the "Doodle" part of the logo, such as OfficeDoodle & DormDoodle.
