Florist Help

I am looking for a quote for:
1. About 22 centerpieces, either low or 3 tall vases with submerged flowers (open to type of flower)
2. 1 bride's bouquet, 7 bridesmaids, 6 boutionieers.

I am looking to use deep purple and orange calla lillies.

I am open to ordering the flowers wholesale myself, and hiring someone just to put the bouquets together and the centerpieces the day of.

Thanks!
