Becoming A Wedding Planner

Hello, I am in high school and am dreaming to become a wedding planner in Boston. I would like to know some college courses to help me with the carrer, but especially I would like to know where I can get started looking for a wedding planner job. I would not like to have my own wedding planning company, just a job as a wedding planner working for someone else. Please help me. Thank you so much for you time.
