Convert Text Browser Game Into Mobile App

Hello, I am seeking to hire an individual experience with Unity 3D or PhoneGap that can convert a text-based browser game into a mobile application for iOS/Android/Windows. The browser game is [login to view URL] an online football manager game. We currently do use Unity 3D to simulate live matches but this isn't something you would have to worried about as our current programmer will do the necessary modifications to support this aspect you would just have to worry about the browser-features which is where you manage your club such as setting up formations, buying/selling players, etc.. The way we would like to work is not allowing access to our server, but there will be an API that will run on the server which I can create. The API would be the middle script that gets the data from our database and sends it to the app and gets the data from the app and sends it to the database. You would request what data you would need and I will create the script so you can have the data. You would then send the data and I will have to create the script to save it to the database. For example: A user selected the option to increase the ticket price. The app will open a url like [login to view URL] and will send some data to this file like who is trying to change ticket price and which zone. Another example: You open the club profile page, again the app will open a url like [login to view URL] and will ask the data that exist in the club profile page. I will have again to create a script to send this data to the app in a form that can read it and display it.
