A note about being conflicted: if you are paying $300 USD or more per month to someone in the Philippines, that is already a good (though not "great") wage. IBM pays about $350-400 USD per month to start, for example.

Outside the country earnings are not taxable to the person doing the work (under Philippines tax laws), and anywhere outside of metro Manila (say Quezon City to Sucat and anything in between) you can stretch your dollar even further.
