Welcome to the business Robert and good luck and best wishes in your career.  The first thing I can tell you is to never tell a client that you are new in the business.  The second and even more important is don't do anything without knowing exactly what you are doing legally and ethically.  What you do as a new agent will stay with you throughout your career.  Get help from your broker or a fellow agent and learn the right way from the beginning.
