Angular 9 + .NET 6 Core Stripe Checkout + Subscription

Hi,
I would like a sample Angular 9 front-end + .NET 6 Core back-end built that will have a payments page built using Checkout from Stripe Payment system to purchase a MONTHLY subscription with a set dollar amount. I need this so I can include the payment pages in the website I am building. Do not worry about authentication as I already have all of that.

Front-end = Angular 9 Interface
Back-end = .NET 6 Core server
Stripe = Anything pertaining to Stripe payment system

The sample website will have the following pages/endpoints (An example of the basic flow: https://u5n7k.sse.codesandbox.io/):
1) Front-end: Subscription selection page - 1 to 3 cards with a title and amount to pay
2) Back-end: Get Session ID from Stripe and pass redirect URL OR failure URL and details why
3) Front-end: Redirect to Checkout page based on Session ID returned from Back-end (Reference GitHub page to see sample data to use to test)
4) Back-end: Build Webhooks for different success and failure situations for payment
5) Front-end: Redirect to success or failure page based on what is returned by Stripe + Back-end - include a link to the Stripe Customer Portal so customer can view the subscription immediately after purchase. I will be using this link in an email generated for the customer as well.

* Please provide an estimated duration in hours to create the solution.
* The main Angular project uses Bootstrap 4 for CSS and design elements
* This project does NOT need to save to a database. It only needs to save data in local variables. The code will be integrated into an existing project, just need the basic code written for that integration.

Important ** - The solution needs to be built with Visual Studio Code and Visual Studio 2022 and at the end I will need to receive 2 folders with each project (Angular and VS 2022 Solution). I need to be able to load dependencies and run.
