Help a family move in Kolkata - 4-hour job

After mold in the old building became a health issue for my child, I found a safe, affordable apartment in Kolkata, and the lease starts on Wednesday. I have two children, a few pieces of furniture and no money for movers. I'm hoping for anyone with a van 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. Even a small gift gets used right away and I'll thank you myself.
