wedding co-ordinators

I'm coming from the UK in March 2009. There are lots of w.co-ordinators on the net....can anyone recommend any particular one?
How soon should things get booked?
Do you often see weddings in Central Park etc?

I'm keen to get things booked then its done!

I am using Exquisite Affairs Productions as my planners and day of coordinators.

Check out their website for details:

They've coordinated weddings at so many NYC venues!

Good luck.
