AdvCash payment gateway -API integration for WordPress - WooCommerce

My goal is to integrate the AdvCash payment gateway into my WordPress-WooCommerce website. I need to expand my payment options and offer a secure checkout for my customers. In order to meet my goal, I need this integration to be completed within a 1 or 3 day. I am very familiar with WordPress and WooCommerce, as I’ve been using them for some time, so I should be able to provide any assistance needed.
