I honestly mean this, I don't care who you hire, but hire a wedding wedding planner.
If it's me - that's awesometastic!!! If it's not me, and it's that competition that I adore, that's great too!
I do sincerely mean that.
But remember you can't go back and re-do your wedding day. So if you are considering hiring someone to help you make your wedding day dreams come true, make sure they are professional.
Look around, interview a couple of planners, my personality is different than the next guy (although I do have to say, that my personality is pretty darned perfect...ahem!)
Don't be scared to look around. It's okay.
