Moving day volunteers: Zoe's family relocating in San Francisco

After mold in the old building became a health issue for my child, I found a safe, affordable apartment in San Francisco, and the lease starts on Friday. I have three kids, a few pieces of furniture and no money for movers. I'm hoping for 3-4 helpers for about four 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. Whatever you can give, even just sharing this page, means a lot.
