Activity for Madeleine

How important is it to have a day of coordinator? I like to be in control. But I also want to be able to sit back and enjoy my wedding day without stressing. Can I rely on friends and family to take care of the little things or should I hire someone?...

Looking for suggestions on good boutiques or stores for an unconventional dress. I don't want to spend a ton of money on something I will never wear again. TIA
