Merit School of Music is a good school. They may have or know of "at home" teachers. My goddaughter went there for 2 or 3 years. I haven't tried Chicago Academy Of Music on 17th, but they may have or know of resources. That's great that he's starting so young! Good luck. :)
These are great ideas, thank you! I also found a site, takelessons.com, where you can look within an area code and see reviews for a teacher, too. I'm going to check out the places you recommended, as well. Thank you!
Follow-up, I tried the takelessons.com and had a miserable experience. Wouldn't stop harassing me after I created a profile, and when I did try to enlist a teacher, the teacher backed out within 30 minutes. Was told I would have someone try and help find a replacement, but no one ever contacted me and I called to get a refund. So, just FYI! Now looking at other options.
