Does she want a full-blown business school within a larger university, or would a small LAC with a business major appeal?
Eckerd is good for the latter - you’d be hard pressed to find a more idyllic warm-weather campus.
For a bigger school she might look at College of Charleston - her stats should qualify her for their Honors College (and merit $), and the business school offers a lot of interesting tracks and a Center for Entrepreneurship. The location offers a great combination of small-city resources and coastal recreation.
You’d probably need a bigger budget for most California options; Santa Clara would be a match, with great business programs, but the merit potential is probably limited. U of San Diego, LMU, and Chapman are a little more generous. Maybe SDSU and SJSU if paying $43K-ish OOS for a CSU is acceptable to you.
Her stats are good for ASU’s Barrett Honors College, which has its own honors business major within the School of Business. Does she want beachy-warm or desert-warm?
