Google Trends Scraper

I need a scraper which creates a list of keywords using related searches as mentioned in? Google Trends? detail page for each keyword.? e.g. If hot trend keyword is 'Sarah Palin divorce',? Google? trend shows palin divorce, palin gets divorce, palin scandal etal. Your software should be able to scrape these words and put them into a file/database.? I am looking for something cheap and quick. I prefer php but desktop solution would do too.? Please post a question if any clarification is required.? ## Deliverables I want it quick and cheap. Plz respond if you are able to deliver quickly.
