django dev-

I need a Django App that’ll allow users to [1] register / login with Google & save their data to MongoDB, [2] create API Endpoints from CSV Files, [3] fetch endpoint data to create one template, many pages, and dynamic content in their frontend, and [4] upgrade to a premium plan & restrict them based on their plan.

Below is an example of an API endpoint that shows the first data, but there are many data in the endpoint:
https://relcanonical.co.uk/api/region/

{
"priority": "A01",
"name": "Northern America",
"country": "Canada",
"state": "Yukon, CA",
"county": "Yukon Area, YT",
"city": "Beaver Creek, YT",
"nationality": "Canadians"
}

How can we build a fetch script that will work on all frontend frameworks so that the users can use the endpoint data to create ONE TEMPLATE i.e. visit-$country that will have MANY PAGES i.e. example.com/visit-spain and DYNAMIC CONTENT i.e. I like Spain? Any better approach?

The App has a sleek design with an easy-to-understand process, below’s the flowchart:

The App will use MongoDB to store data, below’s the database schema:

The App ONLY needs the backend logic, below’s the frontend demo:

The App will use Stripe Customer Portal so you don’t have to write any code, below’s the doc:

Could you confirm your budget and delivery date in the chat, please?
