Florist help

Currently I'm living in Poughkeepsie, NY, but am originally from Long Island. Our wedding date is set to 9/2/12, at East Winds in Wading River.

Since I'm remote, I'm trying to do some of the investigations remotely, so that when I get a chance to come down to Long Island, I can narrow down some of the people I need to talk to, and am looking for some information for pricing for florists in the area.

I think that we're going to need:
approximately 18 centerpieces
Brides bouquet
Throw bouquet
Bouquet for MOH and 4 Bridesmaids
3 Corsages for the Moms
8 Boutonnieres

Looking to do the colors for the wedding as teal and orange. So I'm thinking the flowers to be white and orange (Flowers can be seasonal, hoping for some Roses and Gerber daisies). Any ideas about how much money this will cost me?
