I notice on your GoFundMe page it says you're in Cleveland, OH? If that's the case, get in touch with the OhioFurs group; there's a really strong car enthusiast community in Ohio as I recall, and you might be able to find someone who can help you out and bring the repair costs down significantly.
While sadly I'm in California, I'm a professional mechanic, and if you'd like to drop me a PM, I'd be happy to discuss the repairs your car needs and do my best to give you a second opinion. Difficult to do from afar, but if I can help save you any money, I'm happy to help. :)
