I really like the concepts that you have put together.
I like #65 where you have put the tag line under the entire logo - so it is bigger. Also, I like that they are wearing ties - however, it does make the it look very busy, which is why I think you took some of those design elements out in #64.
Perhaps you could take some of the colors out - and maybe just use midnight blue and forest green for the people and alternate them?
