Definitely ask a local landscaper, when I have planting jobs I end up with tons of pots that I either have to pay to dump up the street or stockpile them to get a load worth the 30 min drive to the nearest nursery that accepts them. I usually end up throwing the large ones on kijiji and people come grab them from the curb usually the same day I put the ad up. Also if you have a tree farm close usually they have a bunch of pots they don't use kicking around, if they are damaged a little filter fabric will hold the soil in. We usually end up having to make a relief cut in the larger pots for trees to get them out, so they become useless for resale. I wrap it in filter fabric and then just tye the pot with some nylon rope under the rim to keep the shape.
