Becoming A Special Events Planner

I have helped my mom with 4 quinceaneras including my own, i also planned my own baby shower on a budget. I have ideas and information on all the areas you need for an events like this and more. I want to become a special events planner and open my own business and web site, but i want to be certified to do this. I want to do this because these types of events are very hard to do for someone doing the event for the first time. If there is anyway i could get certified please let me know.
