Code a Google Chrome Extension that auto plays roulette

I need someone to develop a Google Chrome extension, that can auto-play roulette. Here is the action that the extension must do: - It must work for [login to view URL] - I enter how much I want to bid - If we lose, the extension doubles the bid. This keeps on until we win again. - When we win, the extension resets and goes back to the basic bid. You are welcome to use other programs, extensions etc. to make this work.
