Particularly in your early placements, clinics may actually consider you more of a cost than an asset. Theoretically, your CI will be spending time helping you learn, making things move slower, causing them to lose money, etc. In addition, you may have very little or no input as to where you are located for your first placement. That being said, I would be shocked if any were paid.
However, there are programs that will pay you during your terminal clinical placement before graduation. At that point you will have completed your didactic education, and while you will be less efficient than a seasoned PT, you will be fully capable (we hope), and some places will compensate you based on this.
As far as making money though, you will probably have to look elsewhere. It's hard, I know. In addition to a 15cr semester, I am also in the clinic 12+ hours per week, and working 22+ in a research lab to get by. It's not fun, but it's definitely doable. OR, just bite the bullet and take out the loans.
