I don't live in or anywhere near Chicago, but here's what to do. Since you live 7 minutes from O'Hare, you are probably also close to Schaumburg Regional and Palwaukee Municipal. Call up the FBO's at each of these airports and get directions and information (such as do they offer flight training), then drive to each and get a look at their facilities.
FBO at Schaumburg Regional: Northwest Flyers
FBOs at Palwaukee Municipal: Service Avaition, Priester Avaition
If you can't find their phone numbers, email me.
Palwaukee is controlled and Schaumburg is not, there are advantages to learning at both, but in the Chicago area, it would probably be easier to depart from a controlled airport. Don't take my word on this because I have never flown in the Chicago area.
Palwaukee is also a somewhat large airport, with 3 runways, and Schaumburg only has 1. The runways at both are of more than adequete length for learning at. You should talk to instructors at each decided then which airport and which instructor is best for you.
