$50 is almost what the average person in Nepal earns in a month, so that seems unlikely.
$50 an hour is low by any other standard, expect perhaps freelancer.com
I've been working in Kathmandu since last 10 years. On average full time programmers here earn 10 times more than that. And for freelancers the average income goes above $2k/month. Parent charging $50 is probably a cost for small "task" of few hours.
