I am having a very simple buffet and will be putting together all the centerpieces and providing the linen, dinnerware, and flatware (very much a DIY wedding). Although, I do not have anyone to set up the reception, clean up afterwards, or cut the cake for eveyone. Who can do this? Will a day of coordinator do these tasks? I dont want to ask the wedding party in case of bad ettiquet, but I need someone to set up/take down/and cut cake. Any suggestions?
