your response - "Oh My God ! do you know how expensive these services are ? Isn't there anything cheaper " -
you want fast transfer, you pay for a custom encoding solution like this, or you pay for a faster "pipe" from your internet provider. I know people paying $2000 a month for specialty pipes to do very fast uploads (and you client needs a fast pipe too).
I spoke with Level 3 at NAB 2013 - you want fast, you pay.
