PHP or .NET , Open-source E Commerce with Pin code-based order processing. Website & Mobile App

It's a grocery-based shop, so the orders created for a group of pin codes need to be processed in a particular center. Product availability is also managed based on pin code. Product should be allowed to add, if the delivery pin code and product availability pin code is same. Give separate quotes for mobile platforms and websites. Message me how you are planning to implement. Will discuss based on feasibility.
