MERN Ecommerce Build (MySQL)

I have a fully-defined visual theme ready to go and now need it converted into a working ecommerce site built with React, Node/Express and MySQL. The store will sell physical goods, so the usual catalogue, product detail and secure checkout flows are required... (Budget: $8 - $15 USD, Jobs: Git, HTML, MERN, MySQL, Node.js, PHP, REST API, Website Design)
