This is a good question. I'd always prescribe to the thought of applying to as many internships as you can, see what is offered, and assess your options at that point. I would also speak with your academic adviser and have him or her review internship options that best suit your needs. There are many internships that do pay a wage. Another avenue to explore can be working with an organization on campus, perhaps even aligning with your academic concentration. Several administrative buildings and programs hire students to do miscellaneous activities that are both flexible with your schedule and will pay.
I hope this helps!
