My concept for consideration. I've read your brief carefully and saw the logos of your competitors as well.
I developed my symbol based on a " Star " , that you are company raise above like a star in terms of standards and service provided to your customers & also " Arrows " which all points inwards to the star where there is a center point " customer " who will be the point of your companies focus.
Now as you see, we can high light the arrow we want in grey to use the best way for branding purposes.
i just gave #158 and #159 for demo purposes on how this symbol can be greatly used for inner departments / services your company offers and how it would look like continuing to carry the brand of the logo / symbol of your company.
