Build Simple Wordpress Plugin - SEO ROI Calculator

I need someone to build a simple worpdress plugin. What it will do: Take a look at this screen shot. It will be an "SEO ROI (return on investment) calculator". They will adjust some settings on the calculator and it will calcualt the results. I can show you examples of how this works. I can provide all the "math" of how this will work. Requirements: 100% all code must be in the plugin. Don't link out to outside scrips or library. Must work on any website where I install the plugin.
