Any idea what you want for the logo? I wish I had the software I need (illustrator) to turn the guy on the bottom left:
into your logo. That stone face would make a great logo! The guy on the top isn't a bad model for a logo either.
This guy could make for a neat logo, too (and this one is already a cartoon with defined lines so it would be quite easy to do). HOWEVER, we would need to get permission from the guy that made it.
