I would like to build an app that can list closest service stores listed in our directory with special price offered for a particular service.
It will have an interface for retail user and another one for store owner who can update their offer with price with date and time and small description.
when the user opens the app it will based on his location show the closest stores and their offer price if any. They should also be able to search by zip or name.
When the retail store owner makes an offer they should be able to update their offers and pay us using creditcard or similar option.
Suggestions are invited for native as well as HTML5 options
