Startup Idea : Street Lockers - to store the things

A situation where you went for shopping grocery and then you have a plan to go to a party/function any. It would be awkward to carry those grocery items along with you the respective place. So, the idea is to have locker rooms across each street of the city where the items are stored for temporary purpose. It is not necessary to go and find the locker room, instead a smartphone application where u pin your exact position and the people working in locker service would come to your place and pick the things from you and leaves to the storage place. If the item has to stored in fridge or in cooling condition it would be done as per the customers requirement. Then when you are done with your work, just using the app order for your things to be delivered to you at the place you need and pay the amount. No need to worry about the things to carry all the way. Life becomes much easier. The payment can be made through the app itself or through cash as per the customer.
