Your brother is lucky to have you looking out for him!
This is by no means a comprehensive list, but here are a few schools that came to mind after reading your introduction.
Universities:
College of William and Mary (more LAC than straight Uni, but it is a Uni)
Boston College
Lehigh University
Villanova University
Wake Forest University
Bucknell University
LACs:
Davidson College
The College of New Jersey (TCNJ for short; public LAC)
I realize that his grades and anticipated scores may not be at the top of the schools listed above, but I believe all of the above schools are within reach, especially if he is able to communicate a strong desire to attend, compose creative and unique essays, and keep a positive grade trend.
