Get data from C# app to Android Os 2

I have one application created by me(i have source code) written using C#. This app have 5 DataTables. Data in this dataTables constantly changes. I have a computer with static IP and unlimited internet connection. This app will work all time on this computer. I want to create Android app which will show all data from this [login to view URL] app have to get data throw Internet. If connection was lost this app have to try to connect once again until the connection will be established. I want this app to be able to send short string messages to the C# app. We will negotiate the design. Ofcouse, the app on android have to work an any smartphone, tablet with Android Os and so on without any problem(corrupted GUI is not acceptable). Data from dataTables have to be sent only if cell is changed. Minimum possible lag required. I am looking for person who be able to create such app and to update my C# code for this. Be aware, that all data in Russian language. I will help you to understand if it will be nessesary. I will release the money after one week for test purpose.
