Modern Business Showcase Website Development

I need a clean, professional website that presents my company online as a polished business showcase. The core pages must include About Us, Services, Contact Us, plus a dedicated area where I can display past project photos alongside customer reviews. I already have a logo and a finalized colour palette, so the design should be built around those brand assets.

A responsive layout that looks great on mobile and desktop is essential, and I want the content structure to be easy for me to update later (a lightweight CMS or clear HTML components—whichever you recommend). Fast loading, basic on-page SEO setup, and an intuitive contact form complete the scope.

Deliverables:
• Fully developed website matching my brand colours & logo
• About Us, Services, Contact Us and Showcase pages populated with placeholder text/images I can swap out
• Mobile-first, cross-browser responsive design
• Simple instructions or CMS credentials so I can make future edits
