Thanks, this is uplifting information, and sounds like a good plan - start with low-paying jobs and be exceptional and then raise your rates and get first-hand clients.
How professional do they handle freelancer's and client's privacy? I will try to do my best but some things can and will go wrong. If things don't go well I don't want to loose my reputation because of some remote-work jobs site, because they or a client skrewed up.
