Sign for a building company

I am looking for a sign that will be placed on a medium-sized window for my building company. I have a specific color scheme in mind and am looking for a designer who can bring it to life. The sign is window signage and I’m expecting a one-of-a-kind creation that will capture the eye of passersby and let them know immediately that they have arrived at a professional business. There will be an inspiring message and logo included on the sign. I'm looking forward to working with a talented designer to create something special. I have a logo already that I want to use attached.
