That's definitely a pretty steep price! I'm thinking you must have contacted one of the top wedding planners in the area :)
If you enjoy wedding planning, I would say maybe hire a day of coordinator or month of coordinator so you can have control of the planning, but then have someone else take care of it for the wedding day or even the month of. But if you are
really busy at work, and don't really have much time or want to plan much, then hiring a wedding coordinator would definitely be a big benefit.
The wedding coordinators do have connections to preffered vendors, so they might be able to negotiate better prices for you, but not sure if the total $ saved would basically pay for itself.
