WordPress Novalcom Payment Redirect

Simple, user make a purchase on site A then is redirected to site B to make the payment and then is redirected to site A again. This is legal business, but my payment service provider only allows me one site.
The site is built with Wordpress and uses Woocommerce plugin

I am looking for a skilled developer with experience in cloaking payment gateways, for example Stripe ( I amusing another provider, but the structure is the same). The project involves cloaking both transaction details, payer information, and order info.

Requirements:
- Expertise in cloaking payment gateways, specifically Stripe and PayPal
- Ability to cloak both transaction details and payer information and order info.
