#5 is nice, but the word REFERRAL needs to be emphsized more than COACH.
#1 is good, but the arc is too high. If we use an arc on this logo, it should be the same as the Referral Advantage log - I guess.
#2 is much like our original logo. I wonder what it would look like in one color.
These are nice choices. I need to show them one of my marketing assistants.
