Ms. Smith's comments couldn't be more off the mark.Most of the work is not being done on-line. In Toronto alone, there are some 600+ studios recording VO everyday, New York and LA triple that. 
To say that the average rate for VO is $250-$300 is completely wrong. 
For instance, in the last 24 hours I recorded two VO projects. One was for 3 ten second TV spots running in regional US markets. This job paid $1800 USD; 10 minutes to deliver. 
Second project was an e-learning narration for a client of mine. 25 minutes of finished audio took roughly 2 hours to deliver. $950 USD.
$250-$300 is what Voices.com pays talent on average for VO and should not be confused with "real" rates for the service.
I have never heard of a college program  for VO. Voice coaching services are sketchy at best and should be approached with skepticism.
80% of the work is done by 20% of pro VO talent out there on the internet. There may be 3 or 4 in Canada making 6 figures.
