Computer Specification Scanner

I need something that returns a report on computer specs. Something that is 'download-free' and done within a web-browser. Something that tests and provides results of the following: Operating System Processor Speed Memory Amount Hard Drive Size Screen Size And if possible Internet speeds. We have certain criteria we need met for a Work at Home position and would like something built where the possible candidate enters their name and email and the test runs in a web browser and the results are either emailed to a specific email or posted on our website for us to view.
