I get this feeling there's a better business model for you. After all it sounds like the market is saying this isn't really worth the effort.
My suggestion, and it's only as half baked as one can in 5 minutes of HN reading: give your book away for free to as many students as possible. Make it clear that you are running a community of social impact students, where networking opportunities will be provided. An online forum as well. You will be sure to have a number of industry people coming to you looking for the best students, which is something recruiters spend a lot of money on.
Someone did something similar in the quant finance space a few years ago, they built an online forum for QF students, got a lot of talking going, and then recruitment became a thing, IIRC one of the early users was a recruitment guy.
Another guy I know teaches a bunch of trading related classes, and he also gets to recommend people for things at fancy firms.
