"Hey,
I'm Nickie, owner of Houston Washing Service. We're looking for someone that can create a simple logo for our Washing Service. I think a lettermark will fit best. Would you be interested?"
Could use a liiiiiiitle more contrast, old eyes might have a hard time seeing it. Also, having the text in the same perspective might help the design to look a bit more cohesive. However, I LOVE the wavy shape you used, your whole design is simple yet conveys some nice motion. Best of luck!
