Google Adwords Keyword Tool - Keyword Scraper

I require a programmer who has extensive skills in developing applications that scrape keyword data from Google’s Adwords Keyword Suggestion Tool. I need a script (c# .net) that will scrape keywords from Google Adwords Keyword Suggestion Tool. IMPORTANT: The script/ software MUST work with http post/get commands (and NOT browser simulation). Basically, a user inputs a keyword, and the script/software would return all keyword suggestions + all searches/month results". I will require you to provide a working sample of the script/software prior to me releasing any payment. This is so that I can verify the correct functionality. - Please only bid you have experience with such applications. I am not interested in programmers who only want to test their skills. - I would require specific verification that you have worked on similar application in the past
