Advertise to your client... not to yourself!
I drove past a truck that had "Window Services". What does THAT mean? They could install windows, they could clean windows, they could repair cracks on car windshields... My point is when doing advertising, advertise for your CLIENT, not for yourself! Just because you know what you do, doesn't mean everybody does!
Ask a few random people who have nothing to do with your business, "Does that make sense to you? Do you know what I do from what that says?"
