If you go for countries with lower wages (just as Boeing did for engineers), you definitely can hire doctors and architects for $9/hour or even less; as $9/h is more than the average doctor or architect gets paid there, you could definitely pick some who are quite decent.
E.g. just to use a random example, Russian statistics show that the average pay of an architect is something like $800/month in many regions - in some more, in some less, but definitely well withing $9/hour; and for doctors in regions outside Moscow it's something roughly similar; Moscow seems to get something like 2200$/month in the average statistics so that's more than $9/hour if they're working sane hours.
