Convert demo website to new charting library

We have a simple one page demo site that displays data from a sensor as a graph using the Open Flash Chart library. We wish to move to using the client side Javascript HighCharts HighStock library , for improved compatibility and better graphs. We will give you full access to the server on which our code resides (MySQL database and PHP. You will need to write an additional page to generate the new graph - like the demo graph at [login to view URL] (with live data) You do not need to worry about the data input or recording side - just the output of this one demo graph. Is successful we will want to extend the project later by further agreement. Please when submitting link or explain why your experience will enable you to get this done quickly and right first time.
