D3 javascript 3D area chart -- 2

I need a custom D3 script created to process data (I will be pulling from wpdb using php, outputting to html as a hidden input value, but will consider creating JSON file for each chart). The D3 script will need to generate a 3D area chart, with some custom rounding at the bottom and two colours to each layer/chart/dataset. I have attached an example of the desired output chart, I will provide further data and an example with example in excel using 3d area charts (however without the custom rounding). The picture attached was generated using a 3D design program, which is resource heavy and not a practical solution for the web server. If you think you can do this is an alternate script, please advise and I will also consider. It will be incorporated into a wordpress plugin, so JS cannot clash with WP. Would be nice to have completed within a week. Similar projects exist on the D3.js example page (or [login to view URL]), however I am happy for existing code to be modified to suit or written from scratch. My preference would be that the code is licensed for open source use. I will do any modifications needed after project is complete, I have worked with D3 on a previous project but this would take me far too long to complete and I have other items to attend to. Note. I have reposted this as costs were unclear for the hourly rate I had previously set.
