Once I've done something similar. We didn't cook/deliver, but each (4 friends) brought bulk fixings (meat, veggies, some sauces, ect...) for 4 portions of 4 different recipes. Then we spent a afternoon preparing basically freezer meals. Each of us went home with one meal from each recipe to stock the freezer. Fix and Freeze Feast is a great book -- (it has some vegetarian as well) It's designed for buying in bulk and preparing and freezing in dinner size amounts to be thawed and cooked. It's also written by a local author.
