most of the 3000 +Liberal Arts colleges and Universities in the US are “well rounded”, i.e. they offer majors in many fields.
you should concentrate your search on finding colleges that 1] you can afford to go to, as well as 2] majors they offer. Many students completely change their minds about what they major in once they get to college - that could happen to you to.
There are FEW colleges beyond Stanford that currently offer “Social Entrepreneurship” type inter-department majors. What you need is a complete understanding of how businesses actually work in order to be able to move into a more narrow area of focus such as S.E.
You are putting the cart before the horse.
