I need help proofreading and updating my website content.

I need help proofreading and updating my website content. I already have an existing website, and the content needs to be transferred to a new website with the appropriate formatting and structure. The work includes proofreading and editing the existing content, updating outdated information, adding new content, creating or modifying pages/tabs where needed, and ensuring the overall content is clear, consistent, and professional. Experience with website content organization and SEO-friendly writing would be a plus. In addition, I need the content for my social media platforms to be updated so that it aligns with the new website, branding, and messaging. The goal is to maintain consistency across all platforms while improving readability and engagement.
