Develop a Mac Application Android application and Website for Bus seat booking. Same design should be there on android and website. Same colour scheme

I want a Bus seat booking service application and website. I am an android and website developer so I know the stuff. Payment will be made only after testing everything, there maybe delay in payments due to promotion of services (It may take up-to 4-5 months) Android : It should be well supported from android 2.3 to latest android 5.1 or which ever. Latest design guidelines should be followed for the design of the application. Navigation drawer, toolbar etc everything should be used of support libraries. Responsive enough. You have to make your own test database and make the application. Original database having location coordinates number of people etc will be provided afterwards. Everything should be dynamic i.e., server based and should be updated constantly while running the application. No crashes should be there. It should support every screen size. Website : Should be very responsive. I will test this thoroughly. Same design as android. Should use same database as android. Mobile Website : Should be very responsive. I will test this thoroughly. Same design as android. Should use same database as android. Budget is little flexible and you can increase the time and have 2 or 3 months. BUT MAKE SURE THERE IS NO COMPROMISE IN QUALITY.
