Create Woocommerce store (or edit the actual one)

Here is the project, I need to create a new Woocommerce store (or edit the actual one) in my page [login to view URL] that looks like [login to view URL] for this reason code customizations are needed for woocommerce appearence, without affecting future updates. Maybe we can make a whole installation inside /tienda to make it easier. Full documentation is needed regarding php, HTMLS, Jquery, css. Making comments. Key characteristics: * Top bar - Search space, contact. * Boxed layout * Fast rendering of the page (google page speed insights - over 80 - gt metrix A) * Customized lateral menu * Custom Footer for the store * Product filters and comparison. * This project is centered in UX design and it has to replicate the functions and the appearence of the model page in all its sections, including the buying process. * A csv with over 4000 products we'll be given to make the initial upload, and making it possible to work with a real amount of products. Please check carefully the model page before making any propossal.
