I recommend you ask at the Health Food Store for any ingredient you can't find quickly. Just about any special ingredient in low carb cookery can be found at the Health Food Store or they can direct you. They will probably have heard of it, even if you haven't.

As for carb counts in recipes, if you are on a low carb plan, you know how to look up the carb counts of ingredients, right? So just look up the carb counts of the ingredients in the recipe, and add them up, then divide by the number of servings. Bingo.

Only the writers of the recipe will have the actual carb counts, so if they're not already there, you will have to do it yourself... and actually, you should do that anyway to be on the safe side, because the counts will differ between brands on ingredients, for example...
