Website Redesign & SEO Upgrade

My current site promotes and sells our own software, but its design and search visibility are holding us back. I need the whole website refreshed with a modern, responsive theme that instantly signals a credible SaaS brand and guides visitors smoothly from landing page to checkout.

Here is what I’m after:
• A complete visual overhaul—new theme, colour palette, typography and layouts—implemented without breaking existing content or download links.
• Streamlined navigation that highlights product features, pricing, support and a clear “Download / Buy” call-to-action.
• Performance-minded development: lightweight code, image optimisation and fast load times.
• On-page SEO baked in from the ground up—clean URL structure, properly nested headings, meta titles and descriptions, schema where appropriate, internal-link logic and an SEO-friendly blog section for future content marketing.
• Smooth mobile experience across major devices and browsers.
• Handover of any design files, theme customisations and a brief walkthrough so my team can add pages or tweak copy later.

Please factor in a short discovery call to review the existing site, then present a staging link before we go live.
