I'm so sorry she is not doing well
If she seems to be in pain, then it's kinder to let her go. I agree with @Engine823 if you are not able to do it yourself then check with other vets to see if they can assist you. I'm still blown away at the $$ amount the vet quoted.
Do you have a father, husband, neighbor or friend that could do it for you. It's hard to do, but sometimes we have to take hold of our emotions and take care of business ourselves. No method is easy, but the broomstick method or cervical dislocation, at least for me, is the quickest way.

I finally got ahold of the local animal shelter & they put her to sleep for me. I cried when I made the decision, but now I feel better. Now she's in peace. The girl at the shelter said she could feel some eggs inside her, so maybe she had some internal laying going on. It didn't look like it to me because she looked so skinny. Must've been painful. They were so nice. They brought her out wrapped in a pretty towel with some pretty plants even taped to it. We buried her just now under the tree outside. I will miss her, but I feel relieved to know she is at peace and pain-free in chicken heaven. 
Poor girl
