If you have a Hospital then  you earn much more than 10k per month. See I think by Hospital you are trying to say that you want to open a Dispensary or a small clinic. In the starting days, it may be tough for the doctors to get patient as all the patients aren't aware about the new doctors. So with time you will surely be able to earn 10k minimum and the maximum can go as high as Rs. 50 to 60 k per month if you become a MBBS doctor.

So nothing to worry about it, you can earn great provided you should keep on studying.

Goodnight :-)
