I need a paywall system implemented for my WordPress-based newspaper site. We have Razorpay activated.

Key Requirements:

- Articles will be the only content behind the paywall

Ideal Skills and Experience:
- Experience with WordPress and Razorpay (subscription setup/trigger)

Please provide demos of already set up systems if possible.
