Even if the software salaries are 250$ per month for devs which is what I read online, I seriously doubt you can find a highly skilled engineer for that price. A highly skilled engineer would only struggle to get the first client on Upwork and earn a lot more or just leave the country.
By highly skilled I mean:
1) Fluent in English
2) Good education - you can't get a great education in isolation it's either from other smart people through online contact or the more likely, face to face(university).
3) Open source projects, ability to pass interview
Even devs would hire a highly skilled dev for 50$.
The whole idea just reeks of americans who haven't left their country.
