Reverse item locator

Instead of going to a shop and finding a list of items available there, the idea would be to find out the list of items around your current location.

Based on the shops location and your current location and your search item, the app would provide you with the options of the nearest shop where your item can be found with the direction details for the shop.

This would help in reducing the time required to identify the item amongst a huge list of shops returned by search items.
Also this would help in doing a more targeted shopping.
Instead of going to a place and finding out that the item is not sold there, this app would reduce your time.
