I would like the logo to look very professional, but still be fun. I'm a loud, outgoing, creative, "get it done" kind of person. Personally, I'm drawn to bright, vivid colors, though I recognize that doesn't always go with "professional."
I'm fine with the logo being made out of the SPP accronym for the company, as long as the company name is within the logo, too.
What would convey "project management?" Organized, methodical, etc.
But I would also like to convey that I take the load off your back. People who hire me will be in need of something -- and perhaps with a sense of urgency. Maybe they have an idea that no one has time to work on. Maybe I would be covering for someone on maternity leave. I might be helping them out of a jam.
I will mostly be using this image on business cards and a Web site.
