In need of affordable self-pay physical therapy for multiple breaks

Here is a little more detail. My girlfriend was in an ATV accident on July 3rd while in Costa Rica. She came back to the states unaware of the extent of her injuries. After racking up a 6 figure bill at Memorial Hermann, she is recovering from 4 surgeries and multiple breaks and fractures being screwed and plated together. Specific breaks are left pelvic ring and left and right ulna. I am trying to find an affordable place for her to do physical therapy since she doesn't have health insurance. Memorial Hermann says they do $125/visit and $150/visit for specialists. We live in Northside, but I work in the southwest so I drive across the city frequently. Any recommendations?
