2. The DJ
If you can't book a proper DJ --- fake it. Find a fold out table to place a laptop and speakers on top of to legitimize a psuedo-DJ-booth. Find a friend or volunteer to handle a Spotify playlist, or for the pro's, make the perfect iTunes mix for your guests to groove to. Make sure to include a special list strictly with instrumentals and beats in case the free styler rappers show up (they usually do) to accommodate easy live entertainment.
