I mean that would be true in the US, but OP explicitly said he's not in the US. It really depends on where he is; 1.5k/month could be considered a very good wage where he is.
That's the wrong way to go about it. You want to be pricing based on supply and demand, not based on your costs.
OP stated he wanted to work remotely, hence he's competing in the global (remote work) market. Many US and other companies hire in this market and often pay US-level (but generally not Silicon Valley-level) salaries. A lot of digital nomad types have those jobs.
Judging by OP's good grasp of English and the fact that he reads Hacker News, I'd say that alone makes him more qualified for those jobs than the bulk of developers from his country. I'd wager many of them don't even compete in that market to begin with.
I concur. Maybe OP prices themselves at $50/hour. That means only 20 hours of work in a month is needed. Lots of people will pay $50/hour. Maybe op has trouble finding full time work at this level starting out. But sure they could find 1/2 weeks work over the course of the month.
