I need SEO expertise for a small project by adding Tag Lines, Key Words & Meta Data to my website.

I am happy with my website design. It was created by Godaddy and they use WordPress. There was zero SEO work completed. They haven't even completed any on-page SEO work which I thoughts was included. I need SEO expertise for a small project by adding the correct Tag Lines, Key Words & Meta Data to my website, which was created in Word Press. I have also written more than 25 high quality blogs should be tied into the SEO work as well. You can view the site at www.beresilient.live.
