;,F: Amelia, what in particular do you have to do as a wedding planner? M;,F: I make most of the big decisions with the exception of more personal ones, such as what the bride will wear or who will be invited. I also booked the venue and the photographer. M;,F: So, do people ask you to organize their weddings to save money? M;,F: Well, I reduce some of the costs. But they have to pay my fee, so it works out about the same.

M;,F: In my case, it was after I'd been doing some voluntary work for a non-profit organization. Others come into wedding planning through different routes, such as restaurant management or providing meals for open air events. M;,F: So how could someone find work in this type of business?
