Write some Software

I am looking for a script that is very precise in catching dropping domains. ONLY if you understand what i am talking about, you can bid... I want you to recommend which registrars to work with and why. ofcourse you should be in knowledge of the techniques used in such scripts, and what time (almost) everyday, each extension drops etc. let me know if you're capable of that, also do you think its better to have it as a desktop application or a web script etc... let me know Thanks
