small pots (3-4") for succulents (Corte Madera (near 101))

I'm tasked with finding 25-30 small pots (3-4" diameter) for a non-profit event (Corte Madera Honors its Nonagenarians and Centenarians). I don't expect to get that 15 or even 5 in one haul. I am willing to pick up just 2 or 3. No plastic and no glass please. Pots without plants are ok. Thank you!
