Walk Easier

I am trying to afford a new device to assist me with walking that won't limit me by requiring special shoes and carrying a control. The new device will assist me in developing a more "normal" gate decreasing the abnormal wear on my hip joint and my back. 
I previously raised money for this device but have been waiting to see if insurance would approve because I did not have enough money. Well insurance won't approve. I have previous monies of $2500.00 but the device is almost $5000.0.
If you could spare even a few dollars it would go a long way in helping me get device. Thank you and God Bless.
