Looking To Buy

Hello, I am a part of a developing party rental company in south east Michigan that is looking to increase inventory in every category including concessions (popcorn poppers, hot dog rollers, cotton candy, etc.), bouncers, games, tables, chairs, and tents. We are looking for suggestions on where the best places to buy from are in our area and on the Internet. If anyone can refer a site or person, it would be much appreciated. Thanks.
