Florist help!

I actually work at a florist, but in the retail end of it and not the event area. I have no idea what to expect to pay for flowers and kinda want an idea of what others are paying. I'm having probably around 130 people (probably around 13 tables), 1 moh, 3 bridesmaids, 1 flower girl, 1 best man, 3 groomsmen, 1 ring bearer, then the mothers and the fathers and 2 grandmothers. I would like some tall cp's and some low, and obviously the extras---petals, decor for the aisle, flowers for the gazebo, etc. I'm doing green and purple flowers and I do like high end flowers.
Thanks so much!!
