Website content developer

I am looking for a website content developer to help me create high-quality material for my website. My primary goal is to sell accounting and tax services, so the content needs to be engaging and informative to convert into sales. I have both existing content that needs to be updated as well as new content that needs to be created, so the content developer should be comfortable with both aspects. My target audience is US CPA firms, so the content should be crafted accordingly. I'm seeking someone with experience in web content writing and SEO, who can ensure that the content is well-crafted and optimized.
