I would get a chamber vaccumm sealer so you can repackage your meats and cheese. You could also package your soups in a bag this way and sell them packaged for the microwave or boil in the bag soups. I had a meat and deli shop and repackaging your meats and cheese will save you a lot of loss. I don’t know your laws but here in the states you have to make your fresh sausage on premise or it has to be federally inspected if it is smoked sausage. For the love of god get a good commercial meat slicer. I think your idea has merit.
Or you receive checks to your business name ,you won’t be bale to deposit them.
