A local chocolate/candy business contacted me to develop some recipes to replace some of their existing chocolates/truffles. They would like to be able to make this in their own shop and would need me to help them with not only developing the recipes, but training them, figuring out what equipment would be needed (possibly where and what to buy) as well as recommendations on production schedules. I am confident I can develop the recipes but I have not done much private consulting. My professional background runs mostly on running large hotel's pastry shops and bakeries. How do I begin to figure out what to charge for such services??
