Sally, does the MS Society in your area have a program where they repair scooters? Some charge based on income....some don't charge at all.
Sometimes the churches around here have programs where members will come to your home to fix things. Some of them have good knowledge of repairing specific things. I'm always leary of letting strangers into my home....even if they are from a church. I tend to not trust too many people regardless of where they are from.
I wish I lived closer to you. I'd come help you! Not sure how much actual
help I'd be but we sure could have fun trying to figure it all out!
