Power Chair Repair

I have been fighting to heal a wound on my foot for 3 years now. The doctor says it is a diabetic ulcer. Unfortunately I have lost the fight and will have to have my leg amputated. As of now, it is a below the knee amputation. I have acquired a power chair to help me get around after the surgery. It has a couple of things that need to be fixed. I have to take it to a repair shop to have them fixed. I am on disability and don't have the funds to have the repairs done. I am meeting with the surgeon on Dec. 30th to discuss the surgery and set a date. I was told it will be about 3 weeks out for the surgery. Anything will help. Thank you in advance.
