Help Kodi Get His Eye Removed

My precious 11 year old dog has to get his left eye removed due to a possible tumor that could very likely be cancerous. The vet said usually cancer in the eye stays located there, so we're hoping for the best! He's also completely blind in that eye due to the pressure being so high that it damaged his optic nerve. So not only is it useless to him now, it is causing him pain. The vet said it's kind of like having a constant headache, it may not be too painful, but it's definitely uncomfortable. I've attached an image that shows the estimate that they gave me. I'm not looking to get the entire amount, but maybe just enough to help cushion the cost. Any help, even just sharing, is greatly appreciated! I've never done this before so it's definitely a first, and hopefully a last, for me. Thank you so much!
