Cricket Fantasy Game App Development

I want a fantasy games app development like dream11. There should be many games like cricket where users can make their own team and points to be calculated similar to dream11. There should be rummy game, there should be Ludo game. There should be teen patti. There should be user panel and admin panel. There should be Payment Gateway integration. User will have to download our apk from our webpage and play it. You will have to make arrangements of payment gateway. User should be able to deposit and withdraw money also. Admin should be able to see all database in Excel sheet. Admin should be able to run push notifications. User should get joining bonus on signup. Without successful payment deposit and withdrawal, your work will not be considered finished. Payment will be done in milestones. First milestone will be released only after showing us payment deposit and withdrawal and remaining payment will be done only after handing over the source code to us.
