JS Dev / Node + React

I only need the backend for

- login (email, password and password forgot, google and Facebook)

- register (username, password, confirm password, google and Facebook)

- email verify

- Change Password
- Delete Account
- 2-factory-auth (sms and / or google Authenticator)

How much is this service and how long do you need for them?

The project start is end of may (the frontend is in progress)


NodeJS
ReactJS
MongoDB


Do you need other tools ? (Auto-0 or firebase) i don’t need there because it causes additional costs

Please let me know the cost and timeframe.
