You ll have to market this product personally - that means you ll have to make a visit to each likely store or outlet. Buy a case, and take them to each store and ask the owner to taste a sample of them and explain how much the minimum order is and how much they sell for and what you ll sell a full case for, you sell the case for 50% of what the full retail price is, and get the money before you leave the case. Leave your Business Card with store owner, and ask him/her to call when they need more stock and you ll deliver.
You need to get in contact with retail distributors. You should be able to find many by making a quick google search. They will buy from you and sell directly to retail stores. You can try looking at http://www.varietydistributors.com/ for a start.
