domain information gathering

objective: A program which searches the web for domain names and is constantly searching as fast as possible. Thousands per hour. It will gather information on domains such as its alexis page rank, google PR rating, as well as the expiration date of the domain, and who the owner is. The list will eventually grow to millions. I want to be able to search and sort this list for the domains expiring soon and manually purchase them for now. It will then tell me which have expired 30 days ago so i know which to register. language: must be command line linux based. C++ or else is fine. I would prefer to run this on a linux pc and connect it to a mysql database. Any programming language should be good except for java. It is garbage.
