Cheryl,

Eons ago I worked as a deliveryman for a florist and spent thousands of hours with the owners of the business regarding in-store marketing.

What we learned was that some of the most profitable parts of the business was the sale of two things in addition to flowers:
(1) Cards (birthday, wedding, get-well, etc). Make them obvious to the customers and they will sell. Keep the seasonal cards by the register.
(2) Sales to churches. Negotiate with local churches to have weekly deliveries to the churches for their services. Keep the proces low and make heavy use of Gladiolas. This will impress the churchgoers and bring in more clients.

I wish you well in your new venture. It will be a bunch of work, but it can be profitable.

Also, if you need people to deliver flowers, hire a student with a good driving record and you will be fine.
