SEO-Optimized HTML/CSS Website Build

I need a clean, fast-loading website built entirely with hand-coded HTML and CSS, structured from the ground up to follow on-page SEO best practices. Think lightweight, semantic markup, well-planned heading hierarchy, and fully commented source files that make future edits easy...
