Wedding and Event planners: How did you start your business?

Within the next few years, after my own wedding is over and we’ve moved into our new place, I’m determined to start my own event planning business after being an office event coordinator for a couple years now. I was wondering how you event/wedding planners starting your own business. I plan on stocking up on plenty of event planning business books (event planning for dummies, anyone?), but does anyone else have any advice for me? Where to begin? What’s most important? I’d love to hear it! Thanks in advance.
