Where can I go for low cost immunizations and tests before matriculation?

Hey guys! I will be starting med school in August and am required to have certain immunizations and titers done prior to matriculation. However, I don't have health insurance right now as I can't afford my company's plan. I also don't qualify for medicaid in my state and the immunizations and tests I need are expensive (upwards of $600-$700), so I'm kind of in a hard place. Do you know of any facilities that provide these services at a lower cost other than pharmacies or urgent cares? Thank you!

Edit: I also want to add that my future schools' student health clinic does not provide these services to incoming students so unfortunately it isn't an option.
