Bulk Whois Script

I need a script that will query full whois details from the godaddy whois database at [login to view URL] from a list of domains in a text file that I provide (I can upload text files onto one of my sites if it's easier). Needs to be able to handle 10,000 domains a day. Details need to be parsed into .csv, or csv compatible format, separated by category (name, address, etc.) I will be running the script on a static IP. You will need to come up with a way so that I don't get banned from using this script to do inquiries on a daily basis.
