Simple job - statistical calculator wp-plugin

Build me a calculator in the form of a wp-plugin. You will get the formula/alogrithm and the design elements. At the moment the calculator uses javascript but if you want to use something else that's fine. However I dont want the formula/algorithm to be visible when somebody checks out the source code in a browser. The calculator is basically a copy of www.splittester.com. Check it out to get a better idea of the calculator and how the answers are generated and displayed. Also take a look at the [login to view URL] to get a better idea of what I want it to look like. Before you bid be sure that you have the skills to complete the task and discribe exactly what you will deliver upon completion and how you are going to do it. If you are not sue about something just ASK!!
