Entropion surgery costs

Hey guys. Got a quote for entropion surgery for $4600. There arent many options where I live I don't think. Does this seem like the going rate? His one eye obviously needs it but I kind of want to barf right now. I'll take any words of wisdom or just words as I kind of lose my mind. This cat has been sick since I got him and I just want him to feel better and we're already 2k+ deep in a year so I just want to cry.
