I don't know about florists, but since you don't need a lot of flowers you could consider doing your own. I did mine (my bouquet, 3 bms, 12 bouts and 3 corsages, 20 centerpieces and more) and it was fairly easy. You can order bulk flowers online (fifty flowers, sams club, costco, etc.) or pick up bunches of flowers at trader joe's or another store. PM me if you're thinking of DIYing or have any questions, I'm happy to help.
My sister did her flowers (hydrangeas, roses, filler) for around $1200 and she needed a lot more than what you're planning on. She worked with Magnolia Street Floral in Roswell.
