Publish Expo/React Native App to App Store & Google Play with Developer Accounts

Hello,
We are looking for an experienced freelancer who already has active Apple Developer and/or Google Play developer accounts to assist us with publishing our mobile application.
The application is already developed with React Native/Expo and fully functional. No application development is required.
We mainly need assistance with:
- publishing the app on the Apple App Store and Google Play using your developer accounts;
- handling the store configuration and submission process until approval;
- allowing the app to be transferred later to our own organization developer accounts, which are currently pending our D-U-N-S number.
Important: our source code and infrastructure will remain under our control. We can handle the Expo/EAS builds and provide the necessary files for submission.
Please specify in your proposal:
1. Whether you currently have active Apple Developer and Google Play accounts;
2. Whether you have previously published and/or transferred client apps;
3. Your price for this service.
