I am looking for a list ranking the endowment per student for about 100 colleges. 

I can find endowment statistics, and I can find enrollment statistics,
but I can't find a list ranking the highest endowments per student.

Hi,
It sounds like you just need someone to combine the two lists for you.

For $5.00, you can really only expect a Researcher briefly to try to
find a site that gives you exactly the information you want.  IF you
let us look at the sites you have found, maybe someone can see a quick
way to get and sort endowment per student.

Here is a helpful source, The National Association for College and
University Business Officers

Here a few partial rankings, though none of them have 100 colleges on them:
