Remember to research your computing power against the current difficulty (I've not kept up-to-date with it so I don't know the current numbers). At one time a 10 GH/s device may have been impressive, but I remember there being a big wave of new hardware released recently which probably means you stand little chance on your own with a $50 ASIC.
I'm not telling you not to do it; just to do your research and make sure you're using up-to-date numbers in your calculations and not relying on blog posts from 2013.
