Digital twin platform using Grafana for lifts/elevators

I'm looking for a developer to build an initial proof of concept for a digital twin platform for lifts/elevators. The aim is to create a visual interface that connects to lift data and uses Grafana to display live operating status, floor position, faults, performance and historical data. I want a basic working prototype that can eventually scale to multiple lifts and buildings. Initially, simulated data is acceptable if real lift data integration is not immediately possible. Required skills: Grafana, MQTT/API integration, InfluxDB or similar time-series databases, backend development, and digital twin interface development. Experience with industrial IoT is essential. My initial budget is around £500, so I'm looking for someone who can deliver a small, clearly defined prototype and advise on the best architecture for future development. Please provide examples of relevant projects, your proposed approach, and what you could realistically deliver within this budget. I would like to own the source code and documentation on completion. Thanks, Fraser
