Complete a very-very simple Giftcards e-commerce Webapp (for 2 screens and Logic) created in ReactJs

I have the most simple Giftcards e-commerce site created in ReactJs, I need someone that can work on two screens and Logic to be completed.

Considerations:

The e-commerce site consists of 4 screens.

1. Home: where the catalog is shown, list of gifcards and filters [DONE]
2. Giftcard Details (the user can see the giftcards details selected in home screen, then the user add some information in order to buy the giftcard, some validations required) [YOU NEED TO WORK HERE FROM WHAT IT IS LEFT]
3. Cart (list of giftcards added to purchase) [YOU NEEDED TO WORK ON THIS]
4. Payment and receipt [NOT TO WORK NOW]

The screen and Logic needed are (2) Giftcards Details and (3) Cart.

DETAILS:

- The webapp already has a base and architecture with redux.
- It is already connected to a very simple API.
- The site doesn't use a user session.
- The app uses Redux, and a base project from creative-Tim for material Design.
- Responsive design needed.

This implementation for screens and logic will take very few days, is not complex to do.
