WordPress Business News Blog Setup

I’m building a Business blog on WordPress focused on regular Industry news and I need a polished blog page put together. I want to match my existing website on graphic style.
The hosting and core WordPress install are ready; what’s missing is the look, structure, and the key engagement tools.

Here’s what I need done:
• Design and configure a responsive, fast-loading blog page that matches my brand colours and typography.
• Create the page structure—home, category archive, and single-post template—so I can start publishing news immediately.
• Enable Social media integration on every post for easy sharing across key platforms.
• Set up a Comment section with moderation controls accessible from the dashboard.
• Optimise basic on-page SEO (permalinks, meta fields, XML sitemap, caching) and test across modern browsers.
• Provide a concise handover guide or short video showing how to add future posts, manage comments, and keep plugins updated.

Feel free to suggest a lightweight premium theme or a custom child theme—whichever delivers a professional finish without unnecessary bloat. Include your expected timeline and any must-have plugins you’d use so I can review and approve them quickly.
