There is something I am really liking about your design for Entry #15. It speaks volumes without words. In moving forward, can we add in some design elements to increase the professional edge? Is there a way to simplify this a bit further?
I like your font more than I do entry #20, but it may still be worth playing around with a few other professional/modern looking logos. In my previous company, we settled on this font style ,
