No one's mentioned it yet but why don't you try Fiverr? Just go for the ones with lots of reviews if you're the skeptical type.
This one basically posts discussions on Linkedin groups (50 groups at once using one Linkedin account) by harnessing data from an xl sheet that would have the content (header, topic URL etc.) you want to post. Doesn't need installation - just click start the tool and the messages start getting posted. I'm offering this for $300 along with a 2nd tool that allows you to add specific groups to your account (recommended if you're making bulk postings). Let me know.
Until I dont try and see results, I will not put that much money. If you can prove me it works then I would buy it from you no problem.
