The CMS should allow uploading and managing content, and changing landing page content and design elements. The site should support simple motion graphics/animations/visual effects, include practical anti-piracy measures such as watermarking and protected content delivery, and be fully responsive across mobile, tablet, and desktop. Please share relevant portfolio examples, estimated timeline, and budget. Budget is negotiable depending on experience, proposed architecture, and scope. Preference will be given to developers who can recommend a lean, scalable MVP approach.
