SEO optimisation of existing website

I am not looking for someone to conduct ongoing SEO work, merely an expert who can optimise my website as it stands with tites, slugs, meta etc. Site is built in Wordpress/Elementor with Woocommerce and MYOB plugin. Strictly no SPAM links or false data that could lead to black-listing. I have spent thousands of dollars on the construction of this website and am now ready for optimisation. Keywords can be discussed.

Offers by CHAT message only so I can filter out the bots/auto-bids.
