Even after 20+ years of software development I still learn a lot each time I do a code review or pair program. Of course there's other developers around me where I work so it's a "free" resource.

$20-$45/h seems very low, though. I charge $120/h for moonlighting and I don't think I'm that expensive so you may not get top level talent for <$50

I was going to say, top engineers are paid $100-$200/hr at work. Unless they are doing it as charity work, they would be very unaffordable.

Although if the person looking for a tutor is very junior, then he can learn from basically any senior engineer.
