I am a professional from Chicago who also has a website -- http://smallspaceresources.blogspot.com. I live in a small space (550 square feet) and was always looking around for the perfect furniture that's not too expensive and also clever multipurpose furniture. I started the website as a resource for others in the same situation.

Urban professionals who live in small spaces and who need great resources to help them out.
Logo that I can post on my blog.
I do not want anything cartoony or too flowery/flowing.
I was thinking about how my blog may help you break out of your space - make your space seem larger. So maybe something could be worked into the design about making your space seem larger.
I am probably going to change the design background on my website -- but you could look at it to get color ideas -- I like the colors on it. The address is http://smallspaceresources.blogspot.com
The website sets the tone for style -- so hopefully that will help in choosing fonts and styles.
