Have you ever used www.allrecipes.com? They use scales so that when you find a recipe that you like you can alter the suggested serving size to accomodate your needs. Look up any recipe you think you'd like to make in quantity and then change the scales to the amount of servings you need!
That is my favorite recipe site because not only do they offer the scales but they also allow us to write reviews on the recipes we've tried, rate others reviews, rate recipes, save recipes to a recipe box for further reference and search for recipes by ingredients you want and/or don't want!!! (with free account, of course)
Hope this helps!
