Help a family move in Busan - 4-hour job

After my landlord sold the building, I found a safe, affordable apartment in Busan, and the lease starts on Sunday. I have three kids, a few pieces of furniture and no money for movers. I'm hoping for a few strong people for about five hours. If you have a van or pickup, that would help enormously - I'll cover fuel. The old place is on the second floor and the new place has an elevator. 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. Thank you so much.
