Undergraduate Business Schools

Best education/cheapest price for you is likely to be your instate choices (Bing SOM and Albany) plus universities with either merit that brings costs down to a SUNY or higher ranked/considered business schools.
Look at Miami Ohio, USC Columbia, UCincinnati, UMN Twin Cities, UIowa, UIndiana.
Seconding Wake Forest, Richmond.
Smeal (PSU) and Gabelli (Fordham) would be worth a look due to good ROI but not sure they’d be affordable if your budget is 25k.
