Completing the creation of an online store on Wordpress with women's clothing

The store is created in Wordpress, on the Woostify theme. The store already has the basic features in the computer version, which I created independently. However, working full-time, I no longer have as much time for this, as well as motivation.

The store is put on the domain efama.pl

What the store is missing:

- https plug-in

- plugging the rules of the store, privacy policy

- template for mobile devices

- payment gateway

- corrected footer

- improved product page

- improved product category page

- "About Us", "Contact Us" tabs

- option to add a product to the "Favorites" section

- some add-ons of the theme do not have automatic translation to pol

I would also appreciate advice on the topic:

- buying a suitable server (the current one is the cheapest, which probably will not carry a fully functioning store),
