Just to let you know that I am thrilled to be working with you. I have had bad experiences with all kinds of plumbers, carpet people, painters, etc. I am very busy with my work and I need to know that when I recommend someone to my clients that I can count on them to come through for me. I do not have time to babysit.
I appreciate your enthusiasm and professionalism and in turn will direct all my business your way. It is both a comfort and a treat to hire someone who I and my clients can rely on, after all it reflects back on me.
Thank you, I look forward to working together on many projects to come.
