The costs associated with the type can be all over the place so I suggest you try the link suggested above and also call CAE & FSI for quotes. Keep in in mind that your buying a Gulfsteam V type rating with 550 and 450 differences, at least that how it works under FAA rules. To give you an example of the extremes, my GV/450/550 Type rating package costs $29,000 at FSI and my partners same package was billed out at $72,000. That was eight years ago so the numbers have changed some I'm sure.
