need help with flowers...

Next Thursday we have an appointment with the florist from our RH. We are meeting her because with the florist the hall reccomends, they have CP available between 25-35 bucks a piece, they kind of give you a deal. I'm wondering what a decent budget is for flowers.

Heres what we have:

1 MOH
3 Bridesmaids
1 Best man
3 Groomsmen

aprrox 12 - 13 tables (we think)

Do the dad's get boutineers and stuff?
Who gets corsiages?

We haven't chosen bridesmaids dresses yet but I'm sure they will either be like a light brown color or a pink color. I really just want pink roses for the girls...

Is $1500 a reasonable budget for this size? Do you think I could do it for less?

Also, would it be strange to just get CP's from her for the decent price and get bouquets elsewere?
TIA! - Stacey
