Dynamic Lead-Gen Website Build

I need a modern, fully responsive website whose primary purpose is lead generation. The site will feature a clean product catalog that I plan to refresh about once a month, a conversion-focused contact form, and a simple blog area to help with ongoing SEO.

Behind the scenes I want an admin panel that lets me handle user management without digging into code. Content management and an analytics dashboard could come later, so please structure the backend with those potential add-ons in mind.

Visual design should feel current, load fast on mobile and desktop, and follow on-page SEO best practices (schema, meta tags, compressed media, etc.). I’m open to the stack—WordPress with a custom theme, a Headless CMS with React, or another reliable solution—so long as it meets these goals and can be handed over with clear documentation.

Deliverables:
• Live responsive website with product catalog, blog and contact form
• Admin panel with working user management functions
• SEO-ready code and on-page optimization implemented
• Written hand-off guide (and quick screen recording) showing how to add products during the monthly update cycle

Please include examples of similar lead-gen sites you’ve built and note any tools or frameworks you recommend for long-term maintainability.
