Getting driving license for car (Oslo)

Hi,
I'm planning to get driving license in Oslo.
Can someone help me with driving school contacts? near to Lysaker/Lilleaker

I have been driving car from 8 years in India, assuming that I wont fail in any of the tests(hope im not sounding over confident :)), how much does it costs to get a driving license? including classes,test etc..

If there is already a thread with required information, please guide me to that.

Any related information which you think can be helpful to me , please share :)

Thank you!

Cheers
Prasanna
