I've started looking at
www.freelance-design-job.com and it's going to be as good as the others, I think. The great thing about this one is there aren't as many people placing bids yet. So it gives you a better opportunity (if you're good) to get more jobs.
I've been freelancing for a few years now and love it. It works well for family life for me. It's only been in the past few months that I've started looking for odd jobs to fill my lulls on these freelance websites. I've had mostly good experiences. One no-pay. (Which was very frustrating!) But luckily it was for only a small project so I didn't waste too much of my time for nothing.
