Payment Gateway Analysis for Lead Generation Pages

I am currently looking for a professional who can analyze various landing pages to determine the payment gateway being used.

Requirements:
- The landing pages in question are primarily used for lead generation, not e-commerce or event registration.
- I expect the findings to be presented in a detailed report format.

The ideal candidate for this project:
- Should have a solid understanding of different payment gateways and how they are typically integrated into websites.
