Bug fix Android made app

I have had an app created but the current dev team is on lockdown in india and cannot complete the bug fixing of the app. I am now looking for a new DEV who can complete the bug fixes. The app is adult industry related. There is also a feature i require to be added into the app. Feature is: When a user selects an employee for a job, if the employee declines the job, the user gets a push notification (and email) stating 'This employee cannot fulfill the job. Please select another employee' then the app searches for available girls (who have availability in their calendar) and recommends 3 for the client to chose from. Will be discussed in more detail with winning bidder. I have the JAVA source code for you to edit then convert to android APK to send me to test the bug fixes. Bug fixes required are: * A few fields in signup are not to be editable * Date format to be changed in signup page * Profit calculations to be fixed per individual client * Toggle of profits made to be day/month/week/year * Fields in Job Card history are incomplete/not showing for client and employee. Needs some adjusting * Surcharges field needs to be shown on services. It seems to be hidden/has vanished since last update the old devs made * Slight change way payment is made. Currently when job is booked, the client gets charged to credit card. This needs to be held till the employee(s) have all accepted the job. Once accepted, the job is to be charged. Until then, the credit card entered should not be charged. This all needs to be done within 7 days of winning bid. If finished earlier, you will be tipped. Bug fixes are not long jobs, but the new features required might be. The right bidder requires to be available to do future work for the app as i am looking for someone who can be available for fast changes and additions to the app.
