I have worked for Paid Posting Tools, and one thing I can say is that there is absolutely zero communication between the writers and the company hiring them. I don’t even know the names of the people that I work for, let alone what they really want out of writers. I really don’t even think they gave us a way to contact them if we need too.
The writers that they do have are pretty good quality. Most seem to be older women with children, mainly stay at home moms, and quality is decent. Not sure if I would recommend them though, I have heard a lot of things from unhappy customers in terms of consistency.
It’s basically a compilation of several different posting companies, so prices vary. You can visit the site here if you want to check them out.
