We are having an outdoor ceremony in June with about 140 people. Our DJ recently contacted us asking if we wanted to add a ceremony sound system (3 mics & speakers) for $500. After researching a bit, it looks like we're going to have to add mics if we want our guests to actually hear anything going on.
My question is, is $500 about average for ceremony sound? I realize there's extra setup, teardown, etc, but it's going to be for like 20 minutes! I'm just so exhausted by all these little extras that keep piling up.
