WANTED: Wheelchair FOR RENT or SALE - $50 (Madison)

I am seeking a simple wheelchair that I can buy or rent.
I am preparing to have surgery and I need a wheelchair to have my spouse able to transport me.
I will only need it for a week so I am hoping to just rent one.
.
It will be very lightly used, only once or twice to transport me to the car, and from the car to the house, and that's it.
