Looking For Some Advice :)

I am a 21 year old college student and I have always wanted to be an event planner! For the last two years I have planned and coordinated the parties for the medical office I work at, and I have had a blast and they have all turned out amazing! I really want to get in to this business, but where do I start? One of my really close friends wants to partner up with me in this and so we really just need to know where to start? If you have any advice please let me know! Thanks!
