Different shipping zones and products

I have a problem that I find very complicated. It is like this:
For a shop thjat sells food, I have made a webshop, where people can order food and have it either delivered at home or to pick up. The food however is only possible for delivery in the city where the shop is based. Anyone from outside the postal codes area, can only order to pick up. Now the shop owners want to start selling certain product (like non-food etc.) nationwide and of course charge some shipping costs. But i have no idea how to distinguish these products from the food that is being delivered and charge different shipping costs and also prevent that people from outside the area can all of a sudden order food.

I hope this makes any sense, hard to excplain even. But is there a plugin where I can set all these things per product or product category?

Thanks in advance!
