Northwestern is always on my "recommend" list. I would check out staffing VERY CAREFULLY before accepting anything at U of C. I haven't had any contact with Swedish Covenant for years. I used to pick up transports there, and thought it was pretty decent, but a lot can change in 18 years

.
I the city, I would also recommend Rush and Children's Memorial.
Before making a commitment, make sure you know how long of a commute you will have from work to home. Some areas of the city are virtually inaccessible from other areas, and a 1-2 hour trip home can really ruin one's day!
Good luck!
