what are you building that you are soliciting development labor from fiverr and think $30/h is appropriate for anyone on earth involved in programming
$30/h is a typical rate for a dev on Fiverr, I've been very happy with the value I've gotten from it.
If they delivered a working scraper using Ruby or JavaScript or even a 3rd party service, the output would have been the same.
Also the pool of python devs is so large that shrinking the pool in this way doesn't impact on my ability to find someone suitable quickly
If it's what you know and you're taking it over, though, that makes more sense.
Can you give us some real-world examples that you've seen?
If I was hiring for something more important I would've put more thought into that aspect
So it made time/financial sense to hire them, especially since I don't need this skill for later
