Koda needs a specialist & surgery

this is my koda Bear, he’s been my best friend for almost 12 years now. Recently koda has gone to the vet and had a cancerous tumor removed from his hip, along with 8 teeth and a lump on his eyelid. Then they found a large tumor deep inside his ear.  Our vet referred us to a specialist about 3.5 hrs away from where we live. As of right now we are set to go there mid May. Then they will be going and cutting open his ear and removing the tumor clear down to his skull. They estimated us at just about $2000.00 (ouch) for everything.  I usually don’t ask for help from people but with being a single income household and when it comes to koda i will go great lengths for him. So please anything helps even just sharing this will hopefully help him. 
Thank you from my fur baby and myself ❤️
