February brides - Flowers

Hi I am getting married 2/16/02 and I am a little nervous at the cost of flowers since it will be so close to Valentine's Day and we are on a budget. We have seven girls in the wedding party that need flowers plus a flower girl. With a guest list of 200 people we are more than likely going to have at least 20 tables.I would greatly appreciate any suggestions for florists or any creative ideas for table centerpieces not involving much flowers.Would love advice from other February brides as to what they did and how far in advance they ordered their flowers.
Have a great Thanksgiving all!!!!!!!!!!
