Broken fiddle needs help!

I opened my fiddle case at my gig last week to find my fiddle had a fatal button crack. I was hoping the job would be fairly straight forward, but as it turns out the particular way it broke requires the fiddle to be taken apart, grafted, and reset. Any musician knows that seeing your instrument in this kind of condition is already an emotional catastrophe, let alone the financial burden. The total for the entire job is quoted at $895. As a full time musician, this instrument allows me to make my living, and I have to get it repaired as soon as possible. I play several gigs every week, and this along with other life events has left me pretty strapped in trying to pay for this big of a repair at this time. Any help would be greatly appreciated.
