Sir can you tell me any good idea, for money by which I can prepare of ias in any good coaching. In this time I am pursuing graduation.

Since you are pursuing graduation, first think if you can manage to work, student for UPSC and your university exams at the same time. Else, take a break for a year. Then take up any part time job or something which matches your preparation and go for it. You may also try doing any online jobs (beware of the scams too). Even 3-4 hours of self study and proper revision would do to crack the exam. Make sure you invest your time and money a proper way.
Good luck
