A couple of additional points.
The name of the firm is "Caldera Strategy Group" but we don't need the word "Group" in the logo if it is too cumbersome.
While I don't mind some reference to a caldera (
http://en.wikipedia.org/wiki/Caldera) in the logo, lets not go over the top with volcanos and lava
Finally, I don't want anything too "on the nose" e.g. a chess piece to denote strategy, etc.
I will do my best to give feedback and answer questions as quickly as possible.
