Man if he did that for free then count me in the list of people who are looking for him. That is a really big task and you say that he did that for free? And to top it all you say that you have lost contact information of him? Unblievable.
there is many software & site's are available on net but there is no meaning of that kind of submission this will not give you a backlink to improve your site quality & ranking.
Instead of wasting time in submitting your links to thousand free directories...Submit your links to 10 paid inclusion directory which gives you 100% approval and save your time...
There is a difference between using software to speed up and semi automate manual directory submission and using software to fully automate and hit low quality auto approve directories full of spam. There is no difference between manual submission and software assisted manual submission except the time it takes to do each submission.
I think its not good, If you want submit directory then do manual , Its time consuming but safe and result oriented
