If you need money for something so urgent, you should not waste time with SteemIt.
You need to invest a lot of time in SteemIt before you start earning anything.

What skills do you have? Can you write code, write documents, draw logos and posters for companies? Can any of your skills and/or knowledge be applied on a computer?
Whatever skill you have, apply that over the Internet and start earning real money.
If you do not have skills, just open youtube and start learning.
Do not rely on SteemIt to get you out of Venezuela. It won't.

I hope I just helped you. ;)
