From my experience VA are really difficult to pick. I usually get tasks done by 2-3 people at the same time.<p>The tricky aspect is, that while it is cheap, it takes quite some time to train people to do stuff "right". Even if it is just simple stuff, like find x and add it to an excel file, there are huge discrepancies between different VAs.<p>If you don't have at least to people on one task, the question is if you really want to make somebody understand what their errors were, or if you just pay another person in the hopes they have half a brain and get things right.<p>But the effort of finding the right person is definitely worth it if you can establish an ongoing relationship. If this is not an option, it is almost pointless.
