I write for a few companies. Academic Experts is one. I have not had any problems with them or with getting paid. If that changes I will let you know. I think the biggest issue I see just reading through posts and when things are requested to be re-written is as much on the writers as the company - at least with the companies I work for I can not speak for all. However, sometimes writers take papers out of their league or area of expertise because they think they can wing it or it has a big price tag. Sometime I have seen the papers these folks try to pass off. This is not to say the company should not be more careful about who gets what, but just keep in mind getting a bad paper from a company does not mean all the writers are poor. I get very few revisison requests because I do take what I can write and do it well. The revisions requests I get tend to be minor. The point is, you can get a good writer or bad writer at any given company. But some of us good ones are out there who do work hard to get it right for the customer.
