You can also outsource the task to India for a similar amount, or even less, and get someone who will be better than a high schooler. That's the thing that should make some North American developers nervous.
I don't know about that. I've been approached a number of times by people who tried to outsource cheaply to India or China and then realised half-way through the project it was a mess and now they needed someone to try and salvage it.
It doesn't make me nervous at all. If someone wants to hire developers to build a complex system at $10/hr then I encourage them to do it and see how it goes.
