37916 Mass Keyword Scraper

I need a script where I can upload a text file with a list of broad term keywords. Ex. (this would be contents of the text file) " cars trucks dogs cats football etc " I would want the script to take in these keywords one by one and perform a deep scrape on either overture or wordtracker to provide the most possible combinations of keywords relating to that word. ex. [login to view URL] Type in cars and it will give you 100 responses starting with "car insurance" at the top. Click "car insurance" and you will get many more listings, such as "car insurance quote." Click that and you will get more, like "cheap car insurance quote." and so on.... Well, I want the script to take in the keywords from my initial file, do a deep scrape on each one and output a text file named "[login to view URL]" with all of the keywords in it listed line by line...keyword would be the keyword from the text file. ex. "[login to view URL]" I need functionality so my IP will not be banned by overture or whomever (wordtracker) else when running this script with 100's of keywords. I need ease of use and most of all reliability.
