There are definately health care codes that you have to follow if you plan on selling the drinks commercially. I would do a couple of things first I would go online and look at the history of companies like snapple that started small and I think eventually got bought by Coke I would see how they got started. I think the most cost effective and quickest way to market is to go to an existing manufacture and asked them to bottle it for you and then your responsibility really is in the sales and marketing not the operations - good luck
