Modern Image Showcase Website for Bookkeeping Business

I need a basic bookkeeping website built from the ground up whose main job is to present high-quality images in a modern, clean layout. The site does not require full e-commerce or heavy blog functionality; it simply has to load quickly, look polished on all devices, and let my photography take center stage.

Core requirements
• Responsive, modern interface with plenty of white space so images pop.
• Easy back-end or CMS so I can swap photos and captions myself without touching code.
• Essential pages only—home, gallery sections, about/contact—kept light for speed.
• Smooth image sliders or grid masonry, whichever you feel best fits a minimalist, contemporary aesthetic.
• Basic on-page SEO and image optimisation so large files don’t slow things down.

I already have the domain and hosting standing by, so once the final files/theme are delivered I can push the site live immediately. If you have a preferred stack—whether WordPress with a lightweight theme, Webflow, or a hand-coded HTML/CSS solution—let me know; I’m open, provided the finished product remains easy for me to update. But looking for some cheap options

Please share one or two recent sites where photography is the star. A concise proposal explaining your approach and timeline will help me get this project started right away.
