There is at least one orthodox shul walking distance to Muhlenberg.
OP, I think you need to invert your search. Instead of first looking for colleges with kosher meal plans and daily modern O minyan, you need to find schools that would be affordable and that offer your major. Then you can see which of those offer kosher meals (which is increasingly common–College of Charleston is the latest school to join the club), and which have a modern O community nearby (no idea what the O shul is like in Charleston, we went to Reform services there on a vacation trip because the shul is old and historic and we love davening in that kind of setting–obviously we are not O 
).
I’m concerned that you are going to be applying to schools which you won’t be able to attend even if admitted because they’ll be too expensive. It’s a lot of work to put together a good application. Even with the Common App, it takes time to write good essays. More schools means more supplements, which have more essays. It’s a common mistake for students to spread themselves too thin and apply to too many places. Better to concentrate on a smaller list of schools so you can really make your essays sing.
