Changes, new features, wordpress woocomerce

I have a shop/website www.art-styl-wood.pl in worpress

I need to add some features, sub pages ...

Scope of work:

1 Implement Inpost shipping option (some products will not be able to be shipped with this option, so I would also like to know how to add this option to individual products)

2 Adding the option of registration and login of the user, including with a facebook account.

3 Placing a link to the page on facebook

4 I would like that in the menu , the products tab was expandable and after hovering/clicking showed categories

5 Adding sub pages that would be placed at the bottom of the page:

two categories with subcategories:

Customer Service:

- Cost and delivery time

- Delivery forms

- Returns

Information:

- Contact

- Terms and Conditions (I have the text of the terms and conditions)

- Privacy Policy (I have the text of the privacy policy)

At this point, that's all.
