I used both Elance and Upwork, @goldendawne and @arbitrarykitten. Not being based in the US that was a challenge. Then Upwork blocked me, no, threw me out. I still don't know why. They said I'd contravened some policy - and couldn't tell me what. I was doing nothing different in my bids. Anyhow...

I also found it really hard to bid against other non-first world bidders who's rates were so low that it would have cost me to take the work. I am going to look at these you have suggested, @arbitrarykitten because I would still like some writing decently paid writing gigs. One you haven't mentioned, and where I did get some work was Guru (https://www.guru.com/)
Thanks for the tips :)
