Release 2 on my mobile app in react bug fixing

Hello,

I am looking for a team/developer, who could adjust some changes to my mobile app written in react native.
The app is available on the store, you can have a look here MoTim.app

The tasks to be done in the release are as follows:
- Fix defects:
- Notification not arriving - take out condition for delivery of quote, once timer is active it will always send quote
- Notification will be sent everyday
- Button click on settings instead of click on the arrow
- Make the text a bit bigger
- Make the quote text bigger
- Use a different button for the hour format
- Cannot stop the countdown on android
- Interment the version ID in the settings
- Add Facebook code in the app, to track downloads in the Facebook ads tool
- Add quotes to the DB
- Create an app version to test before releasing to production

I would need the answer for the points below:
- Your experience plus portfolio(last 3 projects)
- Reference from other people you did projects for
- How fast can you start working on the project?
- How much time it will take you to finish?
- Thought about the app, what can be improved/changed?
- What do you need from us to get started?
- Have you worked in an agile environment?
- How do you cope with blockers?
- What kind of programming languages do you know and which one is your favourite?

Thank you and wish you an amazing day!
