You might try a farmers market. but that will not move a large quantity.
You might try the grocery stores: lately it has been popular to put out a box of melons with the sign "Locally grown".
Lastly, when I was selling my blackberries I left some on consignment: If they sold good and I got paid, if they didn't then i would pick up the unsold fruit.
I was never big
enough to go the wholesale route: might your extension agent be of help?
