If you want to be a CFI
AND study for a Bachelors degree at the same time then you da man. All the big schools would probably want to work you full time unless you have a special arrangement. A litttle school probably is best and since they are all over, you can go wherever you want.
My personal experience was in the central valley of california Sierra Academy of Aeronautics KMER. A gleefully diorganized place that worked me 14 hours a day when I first started (not flight hours, work hours). Had to tell them to reduce my load or I was leaving. But free housing and cheap food and all the hours you want.
