Issues with my website https://wildsheboutique.com

I am having issues with my online shop https://wildsheboutique.com/ - I want someone to have a look over the whole site to check everything is as it should be as I am finding many issues which is the reason i am not selling anything right now. it is not optimised the way it should be.

The issues I have found so far -

website loads too slowly . the images on the pages also load too slow and sometimes only load after 2 clicks - needs fixing ASAP

-the image sizing for the products are too small i would prefer them to be bigger like so - https://shop.spelldesigns.com.au/collections/tops

- i want to know how to change the top 4 slider images on the homepage

I want to remove the dates off the blog posts https://wildsheboutique.com/blog/

https://wildsheboutique.com/terms-conditions/ - in the top right there is a #1030 (NO TITLE) i want to take it off

On the homepage the READ MORE button goes to a blank page - https://wildsheboutique.com/elements/pages/about-us/ i want it to land on https://wildsheboutique.com/ethos/

The social icons at the bottom of the homepage some are blue when hovering over them I want them all to be black.

At the bottom of the home page there is payment methods - i want to take this off

I would also like to get a visual editor for the site.

Thanks!
