Adding some changes, fixes to online store - WooCommerce

Good day, I would like to make some stylistic corrections and changes to my online store. Namely:

1. Adding 2 tabs with information made by me.

2. Changing the main images of the site and the color scheme of the site.

3. Changing the delivery information and contact information.

4. Stylistic change of the contact tab (as you can see on the phone, the subtitles overlap).

5. Adding a "gift-wrap" option next to the shipping option.

6. Adding a small block with a photo and description prepared by me, on the home page.

Please let me know what would be the amount of money to do these minor corrections, as well as what would be the completion time and whether all the treatments are feasible.

The whole site has been working for some time and you can buy on it. You can find it at: www.vixie-bizuteria.pl
