If you are working for ISRO, is the position in India or the US? If it's in India 800USD seems quiet fair and not "indentured servitude" as a commentator has suggested.

What kind of technologies excites you? Which city are you in? If it's something like Banglore/Delhi, I would suggest going to some tech meetups and explore what people are doing and which technologies are in demand in your city.

I would suggest you to start freelancing, but pick the technology that really excites you.

Considering that you would be working full time at the same time, that's really important.
