Shopify site customisations

Hi Adeel

I have a new shopify website, and I need optimisations on it.
https://vertical-unit.com/

Some of the optimisations needed are:
1. Language/country selector to be on the menu bar in place of search icon
2. Add sticky add to cart in product pages
3. Add Amazon like 5 stars review section or trust pilot 5 stars in the hero section of products, right below the price
4. Change all images in product page hero section carousel based on color. Example: If user selects blue, then make all images in the carousel blue colored goggles.
5. Change "Sale" tag text to "BF Offer"
6. Change reviews/testimonials section to look like zalando/amazon reviews section
7. Add gif + text instead of image + text to product sections
8. Add delivery by (day + date) right below the price
9. Add % discount right next to price (20% OFF)
10. Link the 5 stars in product hero section to reviews section in the page

I might need a couple of more such optimisations.

Budget is tight, and deadline is tomorrow:
