I’m ready to move ahead on two parallel WordPress jobs and want a single developer who can own both from start to finish. 1) New site The goal is to sell products and services through a clean, modern, fully responsive site. I need you to design, build, and configure everything so that managing inventory, orders, and content from the back-end is straightforward. A fast loading experience, SEO-ready structure, and solid security practices are non-negotiable. 2) Existing site – performance rescue My current WordPress site loads slowly. I’d like a thorough audit to pinpoint the bottlenecks and a clear fix that leaves the site stable, quick, and fully functional across major browsers and devices. Caching, image optimisation, database clean-up, plugin conflicts—whatever it takes, I want to see measurable gains in PageSpeed Insights or GTmetrix. Deliverables • Fully functional, launch-ready • Optimised existing site with documented before/after performance metrics • Brief handover outlining theme, plugin, and optimisation settings for future reference Show me past work that proves you handle both fresh builds and tricky troubleshooting. Please include an estimated timeline and cost breakdown with your proposal so I can compare approaches and lock in milestones quickly.
