Domino and TopTal look like they may be more suitable for more experienced developers.
What is everyone else's experience for finding work at the higher end of the market ($600 - $900 / day)? From my experience I know the demand is out there but currently all of my work comes via traditional recruitment agencies which seems a shame for the companies doing the hiring, since agencies charge fairly big fees.
I have in the past tried eLance, Upwork, People Per Hour, and they all seem to end up overrun with low-end work and low-end clients and whilst there may be some gems in there it ends up not being worth your time to sift through / send propsals because 95% of clients will choke if you mention your hourly rate.
