[Callers] calling weddings

Any advice for calling weddings? I've been asked to call my first one and I don't see a lot of wedding-specific advice online. What do you ask them in advance, how do you approach it, what are good dances to call? I'm assuming that a workshop is impractical, so it's barn dances and maybe working up to a contra by the end? Try to teach a swing? Some advice I've gotten so far: Band - can they play contras, am I DJing instead, if so what kind of music, trad or pop? Floor - make sure it's big enough, get length, width, and surface Sound system - what is it and is there a sound tech? Duration - how long they'll want to dance Dancers - how many, any experienced guests? Special dances - first, parents, bouquet, last? Will the bride and groom dance? (If not, nobody will) Will there be alcohol? (one person suggested doubling the fee if there is) Will many women be in high heels? I welcome any advice! My main goal in taking wedding gigs is recruiting new dancers to our local scene, if that matters. Thanks, --jh--
