Update my shopify Website

1) Need to add contact phone no and mail with a call to action on above the menu, below the advt. banner (see yellow box at top right in the image below) 2) Need to add some creative text at the footer, some fact-based copy to make it more attractive. The copy can be related to the brand, something like trivia. (to be shared by the agency) 3) Replace ‘Shop Now’ button with 'BUY NOW' button which will directly take the customer to the checkout page. Need to add the button on both the homepage for bestsellers and on the shop page for all the products. Need to add ‘Add To Cart’ icon to the products on SHOP page, so that a user can add multiple products from the page itself. 4) FAQ page content needs to be on all the product pages. 5) At the footer need to add 100% secure transaction logos for all the merchants like Mastercard, Visa, American Express, or any other merchants. (to be shared by the agency) 6) We need to add a review section on product pages, where users can review each product on each page. Ingredients to be explained with the use of graphic images also the benefits of each product. (to be shared by the agency) 7) Need to add the logos of the places/E-commerce sites where the product is being sold. The logos will be non-clickable (to be shared by the agency) 8) Need to mention the products have a 100% money back guarantee within 30 days. Testimonials should have more details about the users like their age, occupations, interests, hobbies along with the name. 9) Website font style to be changed. 10) Need to add the option to add Media coverage later.
