Help w/Willie's medical bills

As most of you know, Willie was in a bad dirt bike accident four years ago and was told they might need to amputate his right leg. During his first surgery, the VCU trauma surgeon called Chippenham and said he could save his leg. Chippenham cleaned his leg and placed an x-fix on his leg to keep his leg in place. The following morning he was transported to VCU where he stayed for weeks, waiting for his leg to heal before they could do the actual surgery they needed to. Willie went into surgery hoping to get the uncomfortable x-fix off his leg, only to wake up from surgery to find out he had a bad infection and would be on strong antibiotics through IV, which meant another stay in the hospital for 10 days before they could do the surgery. He finally had surgery to correct his leg and let the healing process begin. He was in a wheelchair for 6 months and he could not get around at all without it. As most of you know Willie, this was very hard for him to fathem that he would not be able to be thebusy body he's always been. We constantly were going back to the hospital for x-rays, check-up appointments, etc. About 2 months later he had another surgery to try and help repair the nerve damage. That did not end up helping, but Willie was willing for anything to help his leg.
A year later, he had a spinal chord stimulater implanted in his back to help with leg and back pain. A month later, the doctor needed to go back in the same spot and adjust stimulater leads that moved and controlled the wrong leg.  At last, this stimulater finally helped enough for him to be able to put a shoe on his right foot (which was a huge accomplisment for us). 
In total,  Willie has had a total of 7 surgeries so far and will be having surgery #8  hopefully in around 4 months to get a knee replacement. Recently he had surgery to take out all of the hardware they placed in his leg so they can prep it for the knee replacement. Doctor's are not sure this will help but are very optimistic it will. At this point, Willie is willing to try anything and everything to relieve some of the pain he has endured the past four years. Willie has been seeing a pain managment doctor for 3 years to try and get the pain under control and continues to see him on a monthly basis. 
Obviously, Willie has not been able to work for four years so we've been living off of my income alone. If you know Willie and I, we do not like to ask for ANYTHING, but i feel the stress that has come from trying to keep up with medical bills, hospital bills, pain managment bills, xrays, medications, wheelchair, walker, etc. has been at it's max and we would greatly appreciate any help we can get. 
I would like to conclude with thanking everyone who has helped us the past four years with Willie's leg recovery. It's been a very long, drawn out process but i feel we're starting to see the light at the end of the tunnel.
