Quick facts about us: everyone is really cool. You get to work with top notch clients. All the developers who work with us are seriously talented: we make sure, since you will need to take a short coding test and show us some of your code before we let you in.
I highly recommend it.
By the way, it's not like oDesk where there is bidding. Bidding is not part of the process. You can set a weekly fixed rate for full or part, or just set your hourly. No haggling involved. Clients know they are getting a developer of a certain quality when they choose us, and they know what that costs.
