I prefer #111 but just 2 colors (prefer blue/black). Maybe "Nexus Accountants" in blue - tag line in black and pyramid start off with blue on the bottom and ending up with black on the top.
Maybe also instead of the symbol being on top - what about to the left instead.
#149 - can u show me the symbol on the top as well - AND can u change blue to a slightly more darker blue and also the symbol start off with the same blue on the bottom as the words, then darker blue middle then black on the top.
also the tag line 'connecting your business to profits" in darker bolder black and italics as well.
