Build a Website for My Business using Node.js and React

Hi Guys, I want a 5-6 page website built for my business. I already have the design ready in an Adobe XD file just need someone to build it for me from scratch. I will need the entire backend in Node and the front end developed in React. The website will require integration with Salesforce, Mapbox & Google Analytics. I will need provision for SEO in the backend and ensure it is fully responsive from the smallest to the largest screen size. The XD files are available upon request. The website will also have a login functionality for my clients to access the dashboard which we will develop in the future.
