The problem here might be how to get the parts. So I will ask the question do you know the manufacturer or is there a manufacturer nameplate and model number? This would be very helpful for any handyman or similar to get [parts and do the work. I am guessing that the reason you a not getting any replies are due to this lack of information. I helped with some similar projects in the past, and actually spent 2 hours of more researching replacement parts, which is time that i am typically no compensated for. You might get lucky with an internet search for parts, and assuming the mechanism has not suffered major damage a repair may be relatively easy. I would get as much info as possible and that try contacting local handymen for repair.
