Lokht is asking for bulk translation services, not asking if it works. Some years ago I had a similar idea and searched for it, unfortunately I didn't find any good option - I needed something with really good translation, better than Google Translate.
Well, my solution was implementing my own software to take each PLR article, send to Google Translate and save output in a text file. It worked for a good time (I translated some thousands, I guess), but Google changed something in your Translate tool and it didn't work anymore.
I'd suggest to check in freelancer websites if there is some developer interested to implement similar tool. It can be a little expensive but, if you are intending to use in very large scale, it's worth.
