Android app for pharmacies network

You need to create an Android application for the application of the pharmacy network. The essence of the application is to simplify the interaction of the client with our database of medicines, as well as feedback from us. Application functions: List of medicines by category and filter (price of the unit / vehicle, name, first new), the possibility of registration or authorization and addition of the discount card existing at the client, a reserve of medication on the product page and add to favorites, addresses and contacts of pharmacies in the city of the client (should be determined by its location), news (promotions and discounts). The product page contains an electronic instruction of the drug, its price, with the possibility of a reserve, as well as an addition to the favorites. In the future, the function of selecting drugs for symptoms and diseases is still planned. The design of the application must be coordinated.
How much can it cost to create such an application?
