The logo should appear modern. It is more of a tech site than a medical site.
It should fit in with Web 2.0 logos rather than hospital/practice logos.
The logo may contain either "ClinicalProfits.com" or "ClinicalProfits" or "Clinical Profits". A small graphical image may be appropriate, but not necessary if the text has a strong design element.
There is no color preference. The site's color scheme will accommodate the logo.
Nobody likes cheesy stock photos, or clip art, so try to avoid those.

I wish I could provide more details, but I really don't have a particular design/style in mind. (If I did, I would create it myself.) I'll be actively engaged in the submission process though, and will try to provide prompt feedback throughout the next couple days.
