Need some help for auto repair to get to work

I'm so c, Virginia

Hi folks, I've been working part time where I can walk to work but I've now gotten a interview for a real job but I need repair work on my car so I can get to the workplace. I've got to be able to be available from 3am thru 11pm so I need to be independent again. The repair shop has given a quote of about $600 for all the work so if anyone can help me out would be appreciated. even a little will go far. Thank you all so much.
