Complain about a post

Can anyone help in giving me some advice of production or selling my Indian Cooking Sauce recipe as I make this curry many times a week over the past years and have had very small negative feedback, and this is usually not sweet enough or colour not the same as restaurants ( I use no food colourings at all ). Basically I have perfected a near British Indian Takeaway Curry Sauce, I have only perefected the only type so far and goes down a treat with everyone, I would love to see this on the supermarket shelf and really make my hard work of perfection pay off, or otherwise I would like to sell at farmers markets but I am unsure what rules there are on hygene for this type of small production as I only cook from home.
