You might try AMI, they have a few campuses. I went into the one here in Philly, and the lady with whom I spoke with spoke to me as if I was stupid. I told her that I was working on my CFI, and she asked me if I: "ever heard of the FAA?" and "what a powerplant is?"
Some of them are during the day, M-F for 8 hours. I'm thinking about going to Teterboro School of Aeronautics, heard its better than AMI.
