Car tune

Hello friends. I use my car to drive all over the country performing. It's a good and well maintained car. But on October 8th, it suddenly wouldn't start at all. After determining the battery was not the problem, after a tow truck, the local, well rated auto shop said a new starter is needed, or the car won't even work. Parts and labor come to 672. Add $18 in cabs to and from plus 60+ for extra lodging in a town I was ready to leave, and I am out a large unexpected amount to get the car back in working order. PS The 672 is for a REBUILT starter, the new one was over 800, so this is the bare minimum of what has to be done. With Covid, I have not been able to work since March  as all venues  nationally are closed so the financial hit is honestly catastrophic. 
   Any help you can offer is appreciated, no matter how small.I just can't do this one on my own. Thanks, Rob
