I wouldn't hire a freelance tester, because it's so important, we all do testing in our business. I expect every freelance developer I hire to test everything thoroughly (and I don't just mean unit tests). They're either full-service, or I don't hire them. I've never heard a single coworker or fellow entrepreneur say, "Gee, I really need to hire a freelance 'tester'." (Or other words that would be more likely, such as 'Q&A specialist'.) That's something people either don't do at all / don't care about, or do in-house because they know it's so important. So, aside from arguments about skills, I don't think there's any demand.
