[TheThinkTank] looking for scrap wheels in Ft. Lauderdale

I have a board member who is a sculpture artist. He's building an installation in Ft. Lauderdale using old wheels. We scrounged up a couple hundred for him to take with him but he's looking for about 30 more this week. Anyone have a line on scrap bike wheels in the Davie, FL, USA area? Non-functional preferred.

Attached a pic of what he's got so far. He needs them this week.Best,
