article submission software

Hi,

Can anyone advice me if there is any article submission software that can pos 1,000 - 5,000 articles per week ?

There is so much in the industry i dont want to waste money buying the wrong software

Plsssssssssss Help

I've used article marketing robot and submitted 400 articles successfully but the pr of most of the directories was not even 1 though if it can give even a single organic visitor i'll count it as a free traffic, i've noticed one thing that most of the directories are powered by wordpress, maybe those are owned by the owner of that software, noh ?
