Look on craiglist. Also, the previous poster had a good suggestion. Tell them you only want a "day of" and see if any of them will offer that. Another option is to trade "day of" coordinating with another knottie on a budget. I am doing DOC for a knottie on my month board at the end of this month. Lastly, if you are VERY organized, hire a friend of a friend. I hired the brother of one of my very good friends as an all around "helper" and a co-worker of a very good friend to be my DOC. But, I would only do this if you are VERY VERY organized. I had a binder with step by step instructions, color coded floor plan, and every single box of DIY items had a label on front of it that was color coded to the binder, so nothing could get screwed up.
