I can't find something for this, but a florist needs a lot of input from the customer. For an online order, there needs to be several options for preferences. Delivery, local, distant, rush. Color and flower preferences, color and flower demands, Vase options, occasion type/ feel (ie. is it for a lover, or a sister) Special notes to the person, special delivery notes.

Sounds like you need a web developer....
Grouped and other product plugins from Woo might help!
