Vet Care Needed for stray cats

I have a community of cats living in my trailer park. I am trying to get them all vet care and especially spayed/neutered. There are also some very friendly ones that I want to get fully vetted so they can be adopted out. This is extremely expensive to do by myself; any help would be greatly appreciated!

I have now gotten 4 friendly fixed and vetted. Treated for ear mites aswell. I currently have a male cat named chunky that is a old TNR he is pretty sick so currently all donations are going straight to his vet care l!
