I want to second the comment about the flagship match program at SUNY Albany. And all the SUNYs, Albany probably has the strongest reputation for Business . . . and for the liveliest campus culture. 
And if you really want to go deep into New England University of Maine will be even cheaper than Rutgers because they will match Rutgers tuition and fees but their room & board costs are cheaper than Rutgers’. They have more than half a dozen Business majors.
