did you have one, adn if so, what did you pay them?
i learned that my florist does this on the side for $60 an hour, adn was shocked that people actually pay this amount (although in a $30K budget, i suppose its peanuts). she told me the last wedding she did, they paid her to sit through the ceremony. her "coordinating" basically consisted of putting out the programs, "timing" the girls as they walked down the aisle, door duty, and setting up the receiving line. she was there 3 hours and made nearly $200 to do stuff that people (IMO) should be able to figure out on their own.
that said, how successful do you think one could be putting an ad out there on craig's list offering to do this type of stuff? would you hire a DOC off of craig's list if they were slighly less than the going rate for a pro (and can you really be a pro?)?
