I like #20 a lot. The skyline doesn't look like Charlotte, however. I prefer the word 'is' to be in all caps and underlined. The house under the city is very good - not sure about the red tag. I want to incorporate more of a customer service aspect which is why I like the hand under the other logos. Thanks for the hard work!
The hands on 48 are good but don't quite look like hands, I had to really look to see what they were. #49 is maybe my favorite now. I still hope to have a subtle "hand holding" gesture without making things seem too busy.
