Hello. With this kind of massive hemorrhage, chance of recovery is very slim, unless operated urgently. Already 2 days have passed, and considering his present senseless condition, it is very difficult to say about his recovery. Urgently consult any neurosurgeon. In Kolkata, Institute of Neurosciences and National Neurosciences Center are good options in private setup, but the cost will be pretty high, considering he will need ITU admission, possible ventilation & neurosurgical intervention. Hope this helps.
