I need a company to help me develop my family alcoholic drink into a sellable product?

I have certain ingredients that will settle to the bottom. I don't know a name of or type of company that helps develop a commercially sellable product.. I can't afford an expensive cost. I need high quality and cost low. I know that's what everyone wants but that is what I need. The mix can be made with or without the liqueur in it. The mix is the real product, the liqueur for the alcoholic version can be purchased from another company. I do not have to make liqueur. It will be a much lower cost if I sold the non alcoholic version first. It would be like selling margarita or bloody Mary mix.
