[Javascript] Open a Chrome tab in bottom right corner behind taskbar

I need to open a chrome tab via javascript from parent window that should be of size 500px X 500px and should reside in bottom right corner of the user starting from behind the taskbar and not above it. Refer to images. I don't want it like [login to view URL] but instead like 2.png. Should be a fast gig for someone who already know this. Anyone coming up with a demo with proposal will be offered the project instantly. Prompt payment. Add "jskiller" to your bid so that I know that you took the pain to read through the description. All other bids will be ignored.
