Advanced React.js ongoing project

I have a React.js app that I need someone to help me maintain. It will involve regular small tasks, mostly clean-up at the beginning and maybe adding functionality in the future.

You must have advanced React 16 experience with functional components and hooks.
You must have reviews on this site for React projects.
You must have Jest/enzyme experience.
You must have Git experience.
You must have Storybook experience.

Tell me your hourly rate, React, Jest, Git and Storybook experience. If you don’t do those things I won’t consider you.
