Website Integration to Property Management System

I have a project involving the integration of a website with a property management system to improve workflow and data visualization. The property management system we currently use is Beds24, and we need specific features and functionalities integrated between the website and the system. To do this, we have settled on a preferred programming language stack: WordPress, REST API, JSON, React, PHP, and CSS. Our goal is to develop a website with seamless integration and precise functionality that will improve the operation and organization of our day-to-day work. The website is a Vacation Short stay Rental Booking site which integrates with various other platforms/ channels. We hope to find a skilled freelancer who can help us make our vision a reality.
