Storage, trucking, development and real estate, and equipment rental is where the money will be in the buildup to the event. Just like a convention, but larger, regarding several of those enterprises. I want to get into real estate development, but financial risks will be needed to be made prior to the actual bid. If Chicago doesn't get the bid from the IOC you will stand to lose tremendously. However, if they win, you are way ahead of the game. I think you buy options and real estate, and sell some of it when the bid comes Chicago's way. You then look for developing tourist money. Tour buses, sight seeing, etc. The big banks and insurance companies are going to make theirs, as are the hotels. You have to look for a niche, and if you know the city and it's history as well as I do, you have to use that knowledge to your benefit. What has worked with the convention/expo business? What worked in the previous world's fairs? There is going to be alot of money to be made here. Pay the prevailing wage, be honest with people, and have some access to cash, and with the right ideas you can do really well.
