I like the concept for #37 and #38 the best of the ones you submitted, the others don't seem to have as professional a feel, they're attractive and energetic, but I don't think they convey the sense of professionalism I'm after. #37 and #38 remind me a little of the "NBC Peacock" especially if we added some colour. I'm also leaning toward more rounded fonts at this point. Thanks for the nice variety of submissions!
