Javascript Injections into Browsers via Software - open to bidding

I require a programmer who is very familiar with Javascript Injections in multiple browsers (Internet Explorer, Chrome and Firefox), that can develop software which will automatically inject javascript into any of the above browsers whenever a user is surfing on the internet. Javascript Injections will be a simple .js file include that will be appended into the current webpage. Your job will be to simply inject the javascript into every webpage a surfer goes to. Here is an outline of the process: User visits youtube video: [url removed, login to view] Once webpage is loaded, your software will inject javascript into the page and render it. For testing purposes (your software must automate this), you may use the following javascript code which will inject an advertisement on the left of the youtube video (copy and paste into the address bar): javascript:(function () { var newScript = [url removed, login to view]('script'); [url removed, login to view] = 'text/javascript'; [url removed, login to view] = '[url removed, login to view]'; [url removed, login to view]('head')[0].appendChild(newScript); })(); Your software must simulate the above process for all the top browsers on all webpages. In your response to this project, please confirm: 1) Which browsers your software will work on (I would like IE, Chrome, Firefox) 2) Which programming language you will develop your software in (C++, C, VB, etc.) 3) Any dependencies you require (MFC, .Net framework, etc.) 4) Which compiler you will use to compile the software (Visual C++, gcc, etc.) I require the source code and full instructions on how to create the final binary. Note that the javascript injection code I provided above may change, it should be simple to modify the JS code and re-create the binary. Thank you.
