WP site changes

Hello, i need to finalize a few things for a clients website. Please apply only with correct budget and if you can work immediatly. Here the tasks: 1. instashow header needs linked to IG account (small CSS change) 2. display on mobile version not yet 100% good, needs some changes with menu. Make sure site looks good in different screen sizes with the banners and menu items can be accessed well. 3. make sure that mailchimp is integrated well (done already i think, just double-check). Bottom newsletter signup works? 4. make small MASTERCARD/ VISA logos at the bottom of page so people know they can pay with this 5. wholesale plugin installed, need login page 7. installed multi language plugin, now need finalisation and hint how to use. 8. link in submenu like YOGA WEAR needs same hover effect with line underneath to indicate that its a link 9. add info of shipping details in single product section (?!) 10. [login to view URL] doesn’t show MAHI logo. WHY? 11. When in wholesale mode it says "YOUR PRICE" but i can not se the original normal price. i want to see normal price too. possible? 12. add two size options for bracelets S and M in shop 13. single product page Increase size of PRICE 14. [login to view URL] as soon as a put reviews on or write something there a grey box appears on the left that looks strange? 15. In my dashboard sometimes have difficulties to edit carousel or so. On other computer works. How can we fix? 6. website speed optimization (image resizing, at very end of course) website is [login to view URL] but you will need login to see. Thanks!
