Floral Prices

Hey.. I am starting to talk to florists, and I wanted to know if anyone knows what a good price is for bouqets, boutineres, and also centerpieces. We are most likely going to have 12-13 tables. Also, we will need flowers for a chupah and of course flowers for the wedding party, moms, etc. Any numbers in the general direction would be greatly appreciated. Since its a winter wedding were thinking the centerpieces would have lots of branches and a few flowers to make it look 'wintery'. Any help would be appreciated. Thanks.
