Flower Questions

I am booking some appointments with florists and am confused by what I need. So far I have
1 bridal bouquet
5 bm bouqets
1 jr bm bouquet
9 boutenierres- groom, groomsmen, jr groomsman, ring bearer
2 kissing balls for flower girls
20 centerpieces
flowers for mantles, card table, cocktail hour

What else? I feel like this is going to be a fortune.

Do you want cosages/bouts for your parents/grandparents?

Do you need arranagements for church?

And, as far as the money goes...you might save some by doing rose petals and votives for the cocktail tables/placecard table. The places I saw all threw that in for free.
