Nutritional facts

Hi, I'm doing the nutrtitional facts table for some chocolate bars. I found in many webpages ( www.nutritiondata.com , for example) some generalized nutrient contents for diferent types of chocolate bars, but I would like to elaborate a specific table for our bars, so I need the nutritional facts of each ingredient and I don't find (in a trustfull source) the nutritional content of the cacao liquor. Can someone help me?Thanks
