I need an executable programmed in a Windows XP & Vista compatible language. It should take a bulk list of domain names and scan them for link popularity using Google, Yahoo, and MSN. To prevent banning it should utilize anonymous proxy servers which can be included in a plain text file (one server per line). It must support very large scans of up to 50,000 domains. It should have options to scan only individual search engines or all three and export to a .CSV file.
The software needs to be written in a demo mode unlocked by a serial number generated specifically for single PC. I'm not sure how this is done but I know it can be. The demo mode can scan 50 domains and not export the results or something similar to that.
I'm not a programmer myself so I have no idea which language would work best. Although it needs to be written so that it will not bog down if someone inputs 50,000 domains.
A similar program exists but hasn't been updated in quite a while. I need these for both myself and resale. If it works I have a few similar projects I could do with the same author.
