As someone who has been struggling while freelancing remotely for about three years now, I'm having many of the same problems getting noticed. I've only been able to land two long-term clients, and the one that's left is starting to fizzle out on me. With 13 years of professional experience, I don't think it's a lack of skill, but just for whatever reason I'll get to the interview stage maybe once for every 50 applications or proposals I send out there, and then almost never get anywhere past that. I can only imagine that even with my qualifications, the sheer number of applicants these listings get (perhaps combined with my unwillingness to work for a rate that's too much below market value) is working against me.
