Revamp Corporate Website Design & SEO

I already have a corporate website in production, but its look, features, and online visibility no longer meet our standards. My primary goal is to improve the existing platform rather than build something from scratch.

Here’s what I need tackled:
• Diseño visual: a refreshed, modern interface that stays on-brand, is fully responsive, and feels consistent across browsers and devices.
• Funcionalidad y características: new or refined components (contact forms, service sections, resource library, etc.) developed with clean code that integrates smoothly with the current CMS.
• Optimización para motores de búsqueda (SEO): on-page best practices, faster load times, structured data where relevant, and guidance on any plugins or tools required to maintain rankings post-launch.

Please keep the current content structure intact while suggesting improvements. I will provide access to the staging environment, brand assets, and any analytics you need. Final delivery should include: updated theme/templates, documentation of changes, and a brief hand-off guide so my team can manage future edits with confidence.
