I would say get him to the teaching hospital ASAP. If surgery is required it will not be without it's risk and it will be expensive. I don't want to scare you but when I lost my little girl to complications after surgery I was told before surgery that the more rapid the onset of symptoms the more critical time was to a good prognosis for the surgery. You will need to be aware of possible complications such as loss of bladder control where you may have to learn to express their bladder this can last any where form days to for life or it may not be required at all. There are no guarantees with surgery. In this area at our VTH the cost range I was told to expect was any place form a low of $1,500 to a high in the $2,500-2,700 range. If you choose not to do surgery either due to the cost or for other reasons no one should hold it against you. You and the vets you work with are the only ones who can judge your companions quality of life and the possible benefit vs risk of the various treatment options.
