Domain Finder

I need a full functional script that finds expired domains. Script looks for .com .net .info .org .biz .eu expired domains. I should be able to search on numerous categories at one time. So, I should be able to search on all the domains with an expired date with the highest number of google links (for example). The script should be web based with user management, payment through paypal, and good html front end. Script Finds: DOMAIN NAME EXPIRE DATE YEARS ONLINE PAGERANK GOOGLE LINKS MSN LINKS YAHOO LINKS OVERTURE ALEXA RANK I should be able to refresh the search at any moment. I know there are numerous scripts out there already developed. So should be easy. Message me with an example...
