I've paid from $40 to $85/hour for contractors, based upon experience and the project requirements. My own time goes for more but I do come down to the top of that range if I catch a long term, low overhead project. I don't do on-site work because I live in remote parts, so I don't know what those folks are charging for their time.
I've done clean-up on offshored projects from low-wage havens, can't say that I'd recommend going that route at any price no matter how low. My perspective may be skewed because I was doing clean-up work and in several cases was compelled in the name of economic efficiency to just chuck the original and start with an empty editor.
