Request for Amplify pricing estimation in the documentation

I would suggest adding more examples including a complete full stack using all the available AWS Services under Amplify Framework, let's say that I am planning to use Amplify to build and host a e-commerce web app, a backend app, adding an auth, datastore, S3 storage, with a small size app let's say using 20 tables dynamodb, or medium size like 50 tables.
And then you calculate all that so I can estimate how much I can budget for this app.
