Create a web page graph for 3 temperature monitors

We use software named ThermoHID ([login to view URL]) on 3 computers. Each computer has one temperature monitor plugged into it. ThermoHID has an option to output to URL. On each computer, we have set the URL to [login to view URL] and if we check the web server log, it sends the temperature, every minute as a post. The server logs show the data received as "[login to view URL]?device=1&sensor[]=t&temp=27.6875&type=C". We need someone to: - Build a PHP script that will take the temperature from the POST command and save it in a database. - Build a web page with a graph with the 3 temperature sensors displayed on it. Maybe a line graph? - Display the last available temperature for each sensor on the page in text format so the site operators can identify what the current temperature is without having to look at the graph - Ideally have a date/time select box so that we can view historic temperatures saved in the database. This seems like a pretty straightforward job, but I don't have the knowledge to build the PHP script. Ideally we get this done today, so we can have the page live for the team tomorrow. Please base your cost on doing it today. So we know you've understood this, please put the words HOUSE PLANT in your bid.
