I know it's hard, but stay positive here. You just had someone effectively offer to put in a good word for you with several companies in your country.

Instead of 'I ran out of money and will have to move back soon', which reads a little negative, try 'Thanks! I live in São Paulo right now, but I'm willing to move anywhere in Brazil for an opportunity, though my funds are a bit low so traveling will be tough. I'll send you an email/my email is in my profile'

We employ someone in Sãn Paulo. Send a resume.
