Domestic workers have been competing with outsourced workers since time immemorial. The winning formula is to just be good at what you do. Outsourced work may be cheaper in salary, but it often comes with significant overhead and indirect costs that negate the salary advantage. In the end, the best value wins, not the cheapest salary. So just charge commensurate with your value: if you charge $20/hour in salary, provide $20/hour of value.
