Please also try a few variants where you emphasize the PM more than the C, the C just stands for Corporation and please try a few that focus on the PM part of the brand. Also please view Vodafone's logo mark (the red and silver teardrop of sorts) and think about flipping it upside down to make more of a single quote ( ' ) mark-- I also like the idea of blue/silver and red/silver as the logo colors. Also look at the CAA logo (Creative Artists Agency) http://ssk.com/wp-content/uploads/2010/03/CAA.jpg
