react native finish my project

I have a working react native project, already is published on playstore, appstore.
Now need to finalize:
- revenue cat payments on android (80%)
- adds on ios and android (20%)
- upload mp3 on android (50%)
- logic fixes
- UI polish

How much do you work for a week of work? full time and halftime

only apply if you are a react native expert with typescript, firebase, in app purchases, adds.

Thanks
