The Cookie Jar Fund

Hello ! So recently I moved into a new place, and I was outside smoking one day and me and my fiancé noticed this little cat sunbathing on a really tall fence, so we just let her be and didn't do much about it, until about 2 weeks after we saw her again repeatedly and then one day she was limping. She limped for a week until I went over to her sunbathing spot and coaxed her into my yard with treats and she just waltzed into the house. She hasn't left since and hasn't been happier I dont think!
So the following days after, I called my vet and got the fastest appointment I could for her, and took her in for her checkup.
I found out afterwards she broke her humorous in her shoulder, which in a cats case is pretty rare, and isn't very fun. She can walk and hobble but she doesn't use the arm other than scratching in the cat box. Her options were to fix her arm; they'd rebreak the bone and replace it where it should be and sew her up and heal it, along with monthly therapy for 2 years OR possibly the rest of her life.  Or we had the option to amputate, which is the route I figured to go as having her limb just sit there is already causing atrophy. 
And then on top of her poor little arm, she's broken 3 of her canines, snapped in the middles or at the root from falling from up high or getting severely injured. So she needs those removed as they're becoming infected from being broken....
Walking out with a grand total of 3000 or a little more...
I don't know why she would be like if she wouldn't had come our way that day. Im glad she did, she's an angel sent for me I swear.
We moved November 1st and saw her that day and she became our Cookie the 10th of December 2020. I love her, if she was someone's I dont understand why they couldn't love her, or take care of her properly at least. She has no faults, she has tricks and doesn't seem like the type of cat to be in pain, but the damage to her body says otherwise.
So that's why I'm here today , to tell you guys Cookie's story I hope you guys can help and we really appreciate everything you do !
