I need someone to optimise my website

Hi! I'm looking for a web developer/SEO guru to jump into my 10+ year old Wordpress blog built in Elementor to help bring it back to life. I have 100s of blog posts which used to perform well and now aren't.

A lot of it is putting more content out there that I want to do but a lot of it is probably behind the scenes SEO and indexing and ensuring posts are getting noticed on Google.

I have lots of blogs that I think should still get some kind of recognition on google and aren't.

I also think my website is clunky and cluttered and want someone to help bring it back to life so that any new content I post will get noticed on Google and perform better overall so all in all, it's a good website.

I'd like someone in the UK ideally so I can discuss ideas freely but open to suggestions.
