Corporate WordPress Site Development

I already own the domain and hosting for my organisation and now need the entire website designed and set up in WordPress with a professional, corporate look. The site has to be fully functional when handed over—responsive on all devices, fast-loading, secure, and easy for my team to update.

Core pages I need built are:
• Home
• About Us
• Contact Us (with working form)
• Services
• Testimonials
• Blog
• Portfolio
• FAQ
• Careers

Please handle theme selection or custom theme creation, page layout, basic on-page SEO, and integration of any essential plugins (security, caching, analytics). I’d also like guidance on best practices so I can manage content moving forward.

Once complete, I expect a short walk-through or documentation covering how to edit text, images, and add blog posts.
