Flowers

I'm pretty clueless when it comes to what flowers you need for a wedding.
I know the place I'm having the ceremony supplies the flowers in the aisle and by the alter

Can anyone give me a range of what flowers run for a wedding:

5 bridesmaidsbo-ks
flowergirl bo-k
my bo-k
6 guys (flower on jacket)
simple flowers for 25 tables

Any help would be appreciated

Thank you
Christen
