I recently acquired Ichigos.com, a 24-year-old sheet music website for anime and video game music. The site has 4,200+ transcriptions, 138,000 annual visitors, and decades of SEO authority built up over its lifetime. It currently runs on a legacy custom PHP/LAMP stack on a DigitalOcean server. I am looking for an experienced developer to handle three phases of work: Phase 1 - Code Cleanup: Replace the previous owner's credentials throughout the codebase including Google AdSense, Google Analytics, Mailgun API, and email references in the SSL configuration. Phase 2 - WordPress Migration: Migrate the entire site from legacy PHP to WordPress, including all 4,200+ sheet music PDFs, the community transcription submission system, and the existing database content. Phase 3 - Redesign: Modernize the look and feel with a clean, mobile-responsive design that is fast, easy to navigate, and optimized for AdSense revenue. CRITICAL REQUIREMENT: All existing URLs must be preserved exactly using 301 redirects during migration. This is non-negotiable. This site has 24 years of SEO authority and any broken URLs will permanently destroy rankings that took decades to build. Please do not apply if you are not 100% confident in your ability to handle this. In your proposal please include your specific plan for URL preservation, your experience with PHP to WordPress migrations, examples of similar projects, your estimated timeline, and your fixed price bid broken down by phase. I am a new site owner looking to build a long term relationship with a reliable developer. If this project goes well there will be ongoing maintenance and future work available. I value clear communication and quality over the cheapest bid.
