You may want to look at schools with honors colleges, which sometimes offer generous financial awards in addition to priority for class registration, research opportunities and access to professors. We know people who got very healthy aid from THE Ohio State’s honors program.
On a different note, research whether you get admitted directly into your desired concentration when you apply to B-schools. I know some schools (PSU comes to mind) where you are admitted to the B-school, but you do not get placed in your concentration until after freshman year. When my nephew went there, the dean made clear that everyone wants finance but there were not enough slots, so only the top x students in each class get it.
If you are in IL, you should focus on UIUC. It is very strong in acctg and respectable in finance.
