Bar Stools

I live near chicago and need about 30 = 35 bar stools. I would like black but anything would help. Backs or no backs. Our wedding reception is in september and the hotel doesn`t have high stools to go with the high top tables. That we want. Any one know of a rental place or a restaurant going out of business, or any restaurant or bar want to rent me some? 20 would even help. Thanks.
