How about some similar designs with A 2 Z in Lettermark Form and "Real Estate Agent" as the slogan. The slogan is intended to represent me personally and not necessarily the company.
I like your style. I especially like the ones you are doing for Teri. For me your design should have - A2Z (Lettermark Form and whatever you decide) - Real Estate Agent - Everything you need from A 2 Z (Slogan)
