Depends on lots of factors - including luck and how bold you are!
I know of an instructor who was teaching a very wealthy chap to fly on a SEP. Client decided to buy a Citation X and asked his instructor if he wanted to be the captain on the X. Instructor siezed the opportunity, did 60 hours in RHS, and then to LHS, with no previous jet experience! I'd imagine the insurance is expensive.
