A simple react native app

A simple mobile app is to be developed using React Native. The app should have not more than 4 pages. Few inputs are taken from the users and the output is displayed. There are few formulas which will help in calculating the values. This project does not require much time, it can be finished in few hours. I am looking for someone who is familiar and experienced in react native. I want the source code also the apk file at the end.
