Wanted: Stackable Chairs

Hi folks,
Wondering if you can help us out with this one?
We are on the lookout for good, stackable non-cloth chairs to use in our drop-in centre and our supportive-housing units.
We could use up to 450 of them if in good condition and easily wipeable.
These could be the older wood seat type, or the newer plastic ones.
Got a hot lead? Email Dan at dan.maxson@siloam.ca or call him at 204-956-4344.
Thanks so much!
