I want to put together a group of wedding and event industry pros for a monthly morning networking event, to look at co-marketing, sharing resources, etc. 

I'm thinking:
Event/wedding planners;
Florists;
Bands/DJs;
Tux, dress, bridal, and formal wear shops;
Hotels, wineries, and other venues;
Caterers;
Limo companies;
Bakeries;
Travel Agents;

If I can find at least five people interested, I'll work on setting up a location, date, and time.
