How do you find clinical experiences as a college undergrad in preparation for med school?

I’m a freshman at Johns Hopkins, and I’m having a really difficult time finding a clinical experiences thats flexible, no cost, and near campus.

I wanted to get a phlebotomy license, its too far and crazy expensive.
I tried to be an MA, the work hours interfere with classes.
I’m volunteering at an HIV Clinic, it cancels to many times and is unreliable.
I used to volunteer at a blood donation center, and it was great. But there isn't one near here.
I want to be a pharmacy technician, the closest CVS Health doesn’t offer training and is also too expensive.

I want to have a consistent one that I can go when I’m available. Any ideas?
