Help a family move in Porto Alegre - 4-hour job

After mold in the old building became a health issue for my child, I found a safe, affordable apartment in Porto Alegre, and the lease starts on Monday. I have two children, a few pieces of furniture and no money for movers. I'm hoping for a few strong people for about six hours. If you have a van or pickup, that would help enormously - I'll cover fuel. The old place is on the fourth floor walk-up and the new place has a ground-floor entrance. We'll do it in two trips. Lunch and cold drinks are on me. I know this is a lot to ask of strangers. I'd be happy to share references from my landlord and my employer. Glad we found this place.
