Help my Sister Jenny with her Medical needs

I'm Lisa and Jenny is my Sister. She means the world to me. I want her to be mobile again and be able to go to the store or get out of the house with her family. She needs a walker that costs almost $1000. Jen cant stand up straight and shes 6ft tall so she cant use a normal walker. Shes had 4 spinal surgeries and shes walking around with broken hardware in her back now. The amount of pain shes in everyday breaks my heart. This walker wont help her pain but it will help her walk. And maybe we will get to see her smile more like you see in her picture. That means more to me than anyone could know. Please help. Thank you!!
