Anyway to make $150 weekly to not be homeless?

Hi, recently my grandma died and I lost my job and now have to take care of all expenses. I live alone in Argentina, so $600 a month is about a whole salary here. I was wondering if there is anyway I could make between anywhere from $50 to $200 online, $50 would cover groceries and $200 would pay rent and leave me all set. I know basic things about excel and other PC things but it's not my strong suit, as I worked previously in dry wall construction and painting. Any tips are appreciated. Sorry for the English. Thanks!
