I wish I could help you in particular with the show you are askin, but I will tell you that I had a similar experience with the same type of show that touted catering to the higher end brides. Forget it. They above all other brides in general deal with some type of co-ordinator who tends to all these details. These brides are just as flustered as those spending far less. In general their weddings are much further removed from you because of the expense-unless you just happen to run in the same circles.
So in light of what I have just written, I will be focusing on the co-ordinater shows. They book not only brides, but corporate shows, etc. where entertainment is needed. They have to widen their horizans to stay in business and not just deal with brides. To date I have not had to pay a dime.
