Hello im Ivan..im from the United States and been living in Paraguay for a few months now, and what i see in the high demand is tutoring in the English language..you can teach basic English which is helpful for students and or people wanting a crash course in the language..because in Paraguay a basic level entry course in the equivalent of a 5th Grade english class can cost up to 100,000Gs. Per 2 hour lesson even more if its a private 1 on 1 course..Good Luck
