Web-Based Dashboard for Proxy Testing

I’m looking for a developer to build a simple web-based system I can control from my iPhone. The system should include a mobile-friendly dashboard with a START button, support up to 30 authorized proxy/VPS endpoints, and run tests in parallel. It should show each endpoint’s IP, connection status, response time, and success/failure status, plus START and STOP controls. Basic authentication and security are required, along with a backend API, VPS deployment, and a clean iPhone-friendly interface. Full ownership of the source code and configuration is required. Please confirm if you can build this, recommend the best technology stack, provide a fixed-price quote, estimate the timeline, and include expected monthly server/proxy costs.
