Install Koha with Payment Integration

I need a full installation of the Koha library management system on a Linux server. This setup should include configuring Plack for improved performance and integrating an online payment system. The payment integration should support credit/debit cards, PayPal, bank transfers, and UPI, with Razorpay preferred as the payment gateway. Experience with Koha, Plack, and payment gateway integration is essential. Please ensure the system is optimized and fully functional after installation.
