Need strong backs and a van: moving Gerrit to safer housing

After the rent increase, I found a safe, affordable apartment in Amsterdam, and the lease starts on Friday. I have my elderly father, a few pieces of furniture and no money for movers. I'm hoping for anyone with a van for about three 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 just one flight of stairs. 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.
