Wix Developer is needed for Ux, Functional and Speed Changes

Good Morning

I am looking for a web developer to make the following changes through a basic e-commerce website (Desktop & Mobile)

1. Implement one lightweight chat through the website reducing time charging.
2. Re-categorize products (Create new categories) and Implement breadcrumbs
3. Delete product sliders and implement a list of products instead
4. Fix website redirects e.g Facebook and get-rid off products that don't below each category.

Instead, we can promote the product with a cross-selling action.
5. Structure a correct sitemap according to each product eg: www.onlineshop.com/woman/jackets
6. Tag the whole conversion funnel (public website and checkout) in GTM and Analytics
7. Fix menu colours and implement a correct menu structure (new options)
8.

Delete banners on each internal page showing the catalog as a principal action
9. Change the layout to a plain one
10. Create a footer
11.

Fix website language (only Spanish)
12. Add a newsletter subscription
13. Create a FAQ's Landing page
14.

Create an offer landing page (connect catalog with this)
15.Add contact information
16. Improve photo quality
17. Add a size guide to each product
18.

Delete products out of stock (they are currently showing up with no sense)
19. Add comments to each product
20. Fix (next) option when seeing the catalog
21.

Ask for an e-mail on the checkout as well as the date of birth (include that)

For this part, could you please relate how many hours would you spend on each task and the price for each task?

in addition:

there is a page load speed problem related to the code, could you please also tell me how much time/ how many hours would you spend on the following and what are the actions:

1. Reduce initial server response time
2. Remove unused CSS
3.

Remove duplicate modules in JavaScript bundles


Please find attached a ppt for the first part of the request.
Thanks,
