Help Lil Bit See Again: Urgent Surgery Needed

The pictures you see are of my baby girl, Lil Bit! I am her owner, Autumn. Lil Bit is completely blind in her left eye due to an infection in her mouth, which is causing pressure on her left sinus, thus the blindness and swelling in the eye. We desperately need the tooth gone that is causing the infection, and the extraction is going to cost $1,200. Please help me to help my fur baby, I love this dog more than I love myself.
