Upgrades and correcting errors in my app

My app is an android app written in java. The applicant should have knowledge of java and server side coding too. I want FULLTIME FREELANCER only working at least 7 hours a day for me. Want all the upgrades finished in an error free way in 15 days. You will also have to correct any other errors seen in the app. MAJOR UPGRADES 1. Only 1 account/household - I should be able to permit more at will if need arises No multiple email accounts 2. Completely permanent ban on users - users should not be able to make another account with another email after the ban. I should also be able to unban. 3. Ad block detection and restriction of app use if ad block detected - user should not be able to use the app at all if adblock detected. 4. Reward only after complete viewing of the ad. Otherwise, no reward and 6/6 claim still decreases in case of incomplete ad view. 5. 6/6 claims not getting subtracted problem should be solved with the server side code 6. I want a automatic/manual payment switch for coinbase from remote configuration. Where I can select automatic/manual payment at will. 7. Rooted devices should be rejected. 8. Firebase push notification is not working. I want one where a user gets notification as soon as they open the app before the user starts to use the app. 9. When I publish an update, user should get a notification when they open the app with update link in the notification. And the user should not be able to use the app unless they update. There are 9 minor upgrades too.
