Automated Crypto Payments Integration (NOWPayments) + Pricing Page Layout

I am looking for an experienced developer (frontend + backend) to:

1 - Add automated crypto payments (USDT) using NOWPayments
2 - Add payment method tabs to the pricing page (Credit Card / Crypto)
The website is an adult content subscription site.
Manual solutions and experimental work will not be accepted.

The goal is to allow users to pay for subscription plans using USDT and have their access automatically unlocked after payment confirmation, with no manual intervention. The integration must use the NOWPayments API, accept USDT only (stablecoin), and correctly implement IPN/webhooks to validate the payment, confirm the correct amount, and unlock the subscription. The payment flow must include a page displaying a QR code, payment address, and exact amount, and properly handle the payment states waiting, confirming, finished, and expired. Manual solutions such as “send the payment and notify us” will not be accepted.

The checkout experience must be as simple as possible, with the minimum number of steps and clicks, optimized for mobile-first usage and fast completion.

In addition, payment method tabs must be added at the top of the pricing page, with only two options: Credit Card and Crypto (USDT). The layout should be clean, mobile-first, with icon + text and an underline for the active tab. When Credit Card is selected, the existing checkout via CCBill must remain unchanged. When Crypto (USDT) is selected, it should initiate the payment flow via NOWPayments.

The Credit Card payment option must be selected by default, so users who want to pay with a standard card do not need to perform an extra click.
