budgeting for flower

All the florists I'm planning to meet with are asking us to have an idea of what our budget is when we go meet with them so that they can work with us to stay within our budget. I have no idea what prices are like for flowers so how do we decide what the budget should be? We have a big bridal party (MOH and BM, 8 other couples, 1 junior couple, flower girl and ring bearer) and we're having about 25 tables (high centerpieces). Plus we need flowers for the church, pedals for after the cermeony, parent corsages, etc...

How do I know what a realistic budget for all that should be? I was hoping those of you who have already set a budget for your flowers would have some advice for me.

Thanks!
