Wordpress landing page with product purchase option

Good day

I have a finished project in Figma to implement on my server in wordpress.

The page is a typical landing page in which there are links to sections (not sub-pages just sections on the landing page:

- about the product

- advantages

- reviews

- contact

- shop/basket

The customer can purchase 3 products on this site in different price variants.

In addition, a blog subpage will be created which I will handle myself in wordpress in the future.

Important aspects:

1. use of plugins/plugins please let me know if they will be installed which ones

2. SEO - it must be clean and readable under SEO

3. security - please let me know what security plugins will be used

4. woocommerce - plugin for purchase

5. mobile version

Please provide:

- cost estimate for the implementation of the site

- send a portfolio of work done implementation on wordpress

- implementation time

- information about the plugins used in the implementation of the site.

Thank you
