Build a complex tool and a simple website

I need someone to build an extremely robust data visualization tool which can help companies visualize construction energy, water and waste consumption. This will be a website that construction companies use to monitor their construction site efficiency. I need someone who can build something very quickly, beautifully And with a robust set of backend features including: - Custom login for each business with multiple users per account with various levels of access IE admin, technician etc.... - Complex data visualization with a completely customizable set of input variables. For example: - Extremely appealing and responsive design Candidates need to have a clear idea of how they would execute on this project. Will you build it in Java? Php? Wordpress with plugins? If you can’t clearly state how you will build this you will not get the job. Future compensation beyond this project is virtually guaranteed to whoever can do this successfully.

This project needs to have a demo ready by MONDAY. I work very fast and have worked with many freelance contractors in the past. I need someone very skilled and very dedicated to get this done over the next few days. Good luck!
