I Would suggest you go about building a client list.
Basically you send out, depending on how much you produce, a 1000 sales letters establishing first contact, asking them to reply via email or whatever if they would like to receive a free sample of your farm products. Then sen out the free sample.
Then offer the products at cost so they can really decide if your farm products are right for them.
Then send out weekly emails or letters stating what you have in stock.
Also, it helps for marketing if you are able to stay in the market longer, so i would suggest preserving in some way so you have staying power in the market place.
