WordPress Business Site Setup

I need a straightforward WordPress business website live on my Hostinger account. The scope is intentionally lean:

• Install and configure WordPress on my existing Hostinger hosting.
• Apply a modern-and-clean theme (free or light-weight premium) and set brand colours/fonts I’ll provide.
• Build four core pages—Home, About Us, Services, and Contact—with placeholder copy that I can later replace.
• Add a simple contact form that sends enquiries to my email.
• Ensure the site looks good on mobile and desktop and loads quickly.
• Connect my domain and confirm the SSL certificate is active.
• Hand over login credentials and a brief one-page guide so I can update text or images on my own.

No complex e-commerce or advanced plugins are required; I just want a polished, ready-to-launch presence that reflects a professional image.
