Experienced Wordpress Developer

I want some work done for my website (Upgrade to see actual info) asap.

1 Troubleshoot: The site currently runs PHP 8.1, and Meta Pixels requires PHP 8.2. However, after choosing PHP 8.2, the site cannot be loaded.

2 Advertising: Install Google Console, Google Pixel, & Facebook Pixel, and ready the advertising.

3 Improve UI/IX: Display prices better, improve site speed, and optimise animation.

4 "Book Now" with Setmore - I've removed Vagarou, now need to register on the Setmore platform and install this plugin

5 Shop by WooCommerce: set up a WooCommerce shop for our products and courses, offer instalments with Klarna, and add affiliate system to collaborate with influencers or anyone who gives discounts while earning commissions. I am also considering installing a plugin for dropshipping.

6 Add a course: I'm designing a new course. Create a page for all courses and a page for this new course. Integrate "Book Now" with WooCommerce for all the courses.

7 Footer: Reduce spacing at the bottom. Add payment method

8 High-quality On-page SEO for local areas

9 Past events album: click the photo (of the event) and pop out a UX friendly album

10 Contact 7 Form Plugin: Form submission doesn't go to my mailbox so I hope to fix that.

Conclusion: I'm not sure if I need to redo the site, please share your opinion and provide a quotation & timeframe.
YES I want your opinion, quotation & timeframe, and we'll talk from there! Many thanks.
