Blog Theme Setup & Customization for existing website

I need a fresh WordPress install configured with a new blog-style theme, then tailored so it feels purpose-built for publishing step-by-step tutorials and guides. Once you’ve installed the theme, I’d like you to:

The website in present not support PHP 8 and the latest version, so the website should work for PHP 8 and the latest version

• Apply a clean, reader-friendly layout that keeps long-form instructions easy to follow on both desktop and mobile.
• Configure intuitive navigation for categories such as “How-To”, “Tips”, and “Resources”, making sure the search and archive pages surface content quickly.
• Adjust colors, typography, and header/footer elements to match my existing brand palette (assets supplied on kickoff).
• Optimise post templates for code snippets, images, and embedded videos so each guide looks polished and loads fast.
• Set up essential plugins for SEO, caching, and backups, then verify everything runs smoothly before hand-over.

I’ll supply hosting credentials, the brand assets, and any premium theme files the moment we start. The job is complete when the site is live, responsive, and all tutorial pages display exactly as designed, with no console errors or layout breaks.
