Dental surgery for senior cat

Asking for help with funding my cats 2nd dental surgery <3 my cat is 18 years young and has multiple health issues, but I need to take care of the biggest issue first asap. She had half of her teeth extracted 6 years ago which cost about $1600 at the time. She's been showing signs of oral pain again recently and the vet quoted me around $800-$1200 to have the remaining teeth removed. I now have a 3 year old so a lot of our money goes into childcare, bills, etc. Any help with funding my cats surgery would be appreciated so so much! thank you in advance :)
