You need to NOT be competing on price, add some other differential (in my case I tried competing on very good English and being on the same time zone as most of the U.S.).

Competing on price or selling yourself to the lowest bidder is a losing proposition.

That said, most of the best Indian devs aren't making that money remotely, they're making a lot more (or at least, I've seen them getting paid a lot more).

I got contacted and worked remotely through Hacker News and, although it didn't pan out (I wasn't a good fit) it was a great experience and I met really good people from around the world.
