Chrome NPAPI Plugin Example

I need someone who can show me (via remote desktop) how to setup a development environment for developing Google Chrome NPAPI plugins. I would then like them to show me how to make a simple hello world application using the NPAPI (c/c++) I'd like the tutorial to basically have one function that takes an input from javascript, and returns an output. So from javascript I'd like to be able to call the plugin extension function "Test" with a variable called "Name", and the NPAPI plugin should return to the javascript function with the value "Hello $Name", at which point the javascript can then alert the response with the name that was given as the input. Budget is $250, this should be really easy.
