Android App Development and Maintenance

This Project duration will be long, so please check all the details before going through - Need to develop an android application, similar to udemy. However udemy have teacher's portal as well, but we don't need that. We need only student's portal, where one can register and can enroll in different available courses, and can go through video lectures. Video lectures will be owned completely by us, so we need an admin panel to upload the videos and perform various small operations, for example, changing the prices, adding coupon code, adding a new course and so on. The android app should be ready in max 45 days, and will publish it. You need to build from scratch, right from development to publishing it, connecting with AWS or any better servers, and so on. Once app is published, you need to be available for application maintenance for a year. You will be paid separately for maintenance a fixed monthly amount similar to salary. Budget for development - INR 15000 Budget for maintenance - INR 5000 per month, so INR 60,000 for 12 months, for a year, but in that, you should be available and make any changes required.
