Need help in locating a Citrus Grove to do a fundraiser?

I always sell fruit for the holidays as a fundraiser. I am searching for prices that are reasonable so I can make a good profit. Do you know of a grove in Florida that has a fundraiser program already in place for organizations to sell fruit? I want to purchase it from the growers in Florida so I will get a good rate so buying from a market or middle man is not what I am looking for.
