Automation Bot needed with an App and Google Play Store using BlueStacks

Your job will be to automate a series of steps via Android. This will be done with accessibility services using Blue Stacks. You will have to: 1. Login with a google account 2. Add a payment method to said google account. 3. Open an app, login to said app and click a few buttons within the app. 4. After that is done, logout of the app and the google account. 5. Repeat the process. It must be flawless and should be able to handle any edge cases (incorrect logins, payment method etc). You must also be able to provide the source code. I am looking for someone who is really good with android and professional. They must be able to finish it within a week at most. More info will be given to you if needed. It will have to support multiple instances, so using a database will be essential. Database must load *Google accounts *Accounts for something else *Payment details So each instance will be able to use details only once, and uniquely. If there are no details in the database left, the script should stop executing.
