Handicap ramp

Im an amputee of my left leg and i recently in june took a bad fall and broke my femur which has left me wheelchair bound until i can get my prosthetic leg back on. Until than i desperately need a ramp to get me out to drs appmts and out for an emergency if needed. They are extremely costly and i cannot afford it at this time if anyone can please help out in any way i truly would appreciate it.
