SEO work on website -- 2

Hi, I’m looking for someone to help me with SEO work on my website. Specifically, I need optimization of my Home Page, targeting specific industry keywords. I will also have existing SEO data available that needs to be utilized in the work. My current website is not being shown on search engines(not on any of the first 5-10 pages) such as google when you try to search for any group names of the products that I sell.

If you’re interested, please get in touch and let me know what you can do for me. Thanks!
