Customers acquisition

I have a small business (cleaning company), and also I have a website for my business. The business is doing relatively ok, but I need to do something to increase the number of customers. I am on Google and Yelp as well. I need someone to give me a guidance and help how to get more customers and expand my business. Anyway, I am open to hear different ideas or methods about how to get more customers. Before applying to this project make sure you can demonstrate that you done this kind of task in the past and you had success doing it.
