Finalize & Review the layout of my WooCommerce Shop

I am launching a women's online clothing shop for the Swiss and Liechtenstein market. I chose to use the WooCommerce platform as it is mostly free, user-friendly and customizable. The website is already live (www.thefrench95.ch), theme and necessary plugins have already been installed. Now I need an expert to check/fix/finalize the entire layout and settings before I start communicating and sharing my url. Preferably who someone has done at least 5 jobs for fashion e-commerce.

A few of the plugins I need help with (see attached mockup and example):

Install Multi Language Widget - There are 3 national languages in Switzerland. I need buyers to be able to select their preferred language for the website (FR, EN, IT, DE)

Instagram Gallery - Integrate the gallery at the bottom of the "shop" page and each "product page" (above the footer). The aim is to share pictures posted on the shop's instagram feed and by buyers. So far I have only been able to integrate it at the top of the page (under the main menue)

Product Filter widget on sidebar - Reduce column size

Product display - Reduce size of "Add to cart" and "Quick View" buttons, align social media share buttons on "Product Page", Remove "SKU" and "Category", display "Related Products" in a slider

Main Menue - Move search button to top bar

Top Bar - Move the contact icon to the right, include "wishlist", "my account", "cart" and language selection icons

Footer - Include sections "Customer Care" (including contact form, terms & conditions, delivery information, return policies) and "About Us" (including sitemap, move the newsletter subscription to right column.

I will provide you more details as we start collaborating.

Thanks in advance
