Single Lead Capture Landing Page

I need a custom one-page WordPress landing page based on content and images I provide, with a clean, warm and refined visual style. The page should be responsive, easy to edit using the native WordPress block editor, and designed to encourage visitors to complete a survey and join an interest mailing list. Scope includes responsive desktop/mobile design, survey and mailing-list integration, image optimization, basic SEO, performance optimization, and installation on the server.
