Upgrade Drupal 7 to 10

I run a live Drupal 7.x site that now needs a full core jump to Drupal 10 (or 11 if you can prove stability) and I want it done within four weeks (End of Oktober / 10th November). My driving reason is better performance, so every decision you make—from database migration to theme migration — has to translate into un-noticeably front-end, supported modules and sam functionality. The admins should still be able to use all functions as before. Key elements that must survive the trip intact: • the existing user-management system with all roles and permissions • our e-commerce setup (products, carts, orders, payment gateway) • an audio-guide section that stores sound files, builds a bibliography around them, and plays the audio seamlessly on desktop and mobile All design, content, and URLs have to move over too, preferably wrapped in a modern, responsive theme that you will implement or adapt so it can work with a theme builder (best choice has to be suggested). Expect to clean up deprecated modules, map fields, rebuild views, and configure equivalent contrib or custom modules for Drupal 10/11 while keeping SEO signals steady. WYSIWYG Edirt functionality needs to perform flawlessly. Deliverables 1. Migration plan and timeline (submitted with your detailed project proposal). 2. A staging environment showing the upgraded site for review. 3. Fully migrated production site, performance-tuned and security-hardened. 4. Post-launch support for any migration-related bugs within an agreed window of approx 4 weeks. Acceptance criteria: every retained feature must function at least as well as it does now, page-load times should improve, and no critical errors should appear in the log after the first week live. Send me your detailed project proposal outlining tools, steps, and how you will hit the four-week deadline. Optional: Follow up workload for a subpage with complex functionality possible ...
