Seo on wordpress and possibly set up new site

I am looking for a VERY experienced freelancer to help improve the SEO of my existing WordPress website. I would like someone who is knowledgeable in SEO and who can improve organic search engine rankings and drive traffic to the website. Additionally, I do not need anything to be set up with analytics and tracking. This project would be for an existing business and would require expertise in getting my website to the top of organic search engine results. My site is 6 years old and may need updating or a new one set up. I am in the UK. I may need it hosted by another provider/server. Currently using Netim. I would prefer someone based in the UK
