Aluminum Foil - Heavy-Duty Large Rolls (Roland Park)

Over a year ago we posted on Craig's list looking for large rolls of aluminum foil for a church kitchen.
Someone had a couple from a restaurant they'd closed and we were able to buy them.
Now we need more.
If anyone has large institutional size rolls of heavy-duty aluminum foil for sale very inexpensively please let me know.
We can use regular width or extra-wide.
Thank you.

Someone kindly wrote and offered to sell a couple of small rolls -- the size you'd buy at the grocery store.
That's not what we need.
We need the huge rolls that restaurants, carry-outs, and commercial/institutional kitchens use.
Thanks.
