Some edits & customization on Magento Template

Hello, I'm running a dev version of my website on magento, please see here: [login to view URL] !! Please read attached brief before you're bidding !! I need a couple of modifications to be done within the next few days, here's the brief : 1. SubMenu a. Fix the css I edited on our custom made sub menu (it doesn’t show all elements) + add a bit of margin between elements b. See how to apply same typo than the navigation. If too large, two lines c. Make sure it’s nice on mobile 2. One Page Checkout a. Fix the region problem in French (deactivate region field) 4. Homepage a. Apply the same style for every slideshow, same than the one in the brief (always display a white block with transparency under) + put the small typo in this color : 747474 5. Template issues a. Fix the problem of the pictures (like the one of the shop on the brief) that are cut when it shows with responsive display like smartphone (we want to reduce it only, not cut the picture) b. Add a bit of margin to the footer (on the left) 6. Social Block a. Design a block like in the brief (it has to be responsive) i. Social icons need a html link (4 icons total) ii. When the visitor mouse over the social icon, we need a hover animation (slide a transparent white block on top, same than the buttons on the slideshow) b. and put it to replace this part of the website (see brief) 7. Product pages a. Deactivate mouse click on out of stock sizes (we want the customer can’t click on it) b. Deactivate image loading when the customer clicks on the size button (right now it loads every time) c. After the product is added to cart, display a message “Produit bien ajouté au panier” in white, in a green (abe4be) lightbox, same than when you remove a product from the cart like this (see brief) 8. Category pages a. Add a menu on the left (first in the list, before categories) to filter by available size. If the client clicks on “M size” he will only see products available in M size in the category
