No matter if you are going to write short articles or long books, you should never begin your work without some guarantee from your clients. Such projects are based on fixed prices, or you can charge on an hourly basis. The hourly job Is less risky as you get your money based on the time you spend. But you are among those professional ghostwriters who charge fixed amounts then never deliver the complete project without having the complete payment. Never forget to get the advance payment of about 50% to get the complete guarantee of the project. Do you agree with the discussion?
