I've mostly corresponded with my WP through email. I started asking questions about floral options and soon received an email from Rosie's assistant who set up an appointment for Rosie to call me. Rosie is incredibly thorough!

She spent over 90 minutes on the phone with me discussing floral and photography. She will discuss your bouquet options as well as any ceremony decorations or reception decorations if applicable. If you are near a computer, she will email you examples while you are talking.
Some of the basic prices she has quoted (all based on the SBP pic I posted):
Petals down the aisle: $65
Columns (to rent the pair): $25
Floral Ring: $125
Globe & Candle (rent): $15
Swag (tulle w/ 3 floral arrangements): $250
Petals for Flower Girl: $15
Floral Arrangements (like in the SBP picture I posted): $100-175 each
