I did consider a dual license, however I don't want to fragment the project, given that it's pretty much "done" and someone would just use a fork from before the license changes anyway. As for offering paid support, I could definitely still fall back on that if I need some extra income, but it takes time. So right now I'm leaning on my graduate research.
One method I have found somewhat successful (but I am still flushing out) through another project, Caddy, is selling sponsorships. They give me some flexibility to put more time into the project to benefit everyone, rather than a single customer.
