I recommend Phase 2 http://www.myphase2.com. Lisa did an awesome job with our flowers and centerpieces.
Three come to mind... Studio Flowers (GB), contact Tammy Baker, Bouchard's (GB), contact Tima Kemp, or Ross at Marshall Florist in Kaukauna. Good luck.
I would also recommend Bouchards! They had great suggestions for me. Also, if you order your flowers through them you can get your invitations at 20% off.
I went to Petal Pusher and worked with Nicole. She did a great job!
I would HIGHLY recommend Bouchard's!!! Tina and Tamara are sisters who run/own the place and they have great ideas and are fun to work with, too! The flowers for my wedding (August 2009) looked exactly as I hoped, and my sister was also very happy when they did the flowers for her wedding in May 2009. They are easy to talk to and understand the need to keep budgets down!
I found a girl who is starting up a florist business on Craig's list...she did an awesome job and was very cheap (I paid about 1/2 of what I was expecting). If you email her (I hope it's okay that I am posting her email, but I figure it's business for her!) and tell her Kristen Sutton recommended her, I think you get a percentage off. She can also send you more pictures (I don't think she has a website yet). Here is a picture in the limo...you can see the bouquets/bouts she did. She did a great job on the unity candle centerpiece as well!
