Is there a good software that helps to manages large numbers of domains (xx,xxx range). I need a software that checks the pagerank, expiration date... that kind of stuff.
Most people, that do professional domain trade do have such scripts, just to get a first raw idea of a large amount of domains and then deciding on wether they are interested in it or not... you might ask a professional trader if he would probably resell his scripts (allthough I doubt people would do) - else than that such a script could be done rather cheaply by a freelancer... no big thing...
Maybe you should ask some competent guys to design a suitable one for you.Then you will benefit from this creative idea.
I found that software "Domain Punch Professional v2" it looks pretty good, but it takes about 30 seconds to update the stats per domain - if I want to update 10,000 domains it will take ages...
