Google Scraper Wanted

I need a scraper that will scrape the organic and sponsored results in Google. This is how I would like the program to work: I type a keyword in your program, for example: "dallas divorce lawyers". I should be able to specify, broad match and exact match. Then I specify which page numbers in Google to scrape, for example I don't want to scrape the 1st or 2nd page in Google. I want to scrape pages 10 through 20. This can vary, this is the reason I need to specify the page range. Then your program will scrape pages 10-20 in Google for the organic listings for "dallas divorce lawyers". Then the final output is a list of websites (I need the url's) from organic listings pages 10-20. Any duplicates should be deleted. Please make sure the scraper works correctly when scraping google and doesn't get my IP banned. There should be a delay between scrapes. Scraper should export data into Excel format and work on Windows 7. You should have previous experience in coding scrapers.
