paulo,
The experience needed for flying a 182 is really an insurance requirement, not that it makes any difference where the requirement comes from because you need it. The plane itself is just a 172 with a big heavy front end, so you need to do a load of landings with an instructor to make sure you don't hit nosewheel first and trash it. The high performance part is no big deal, you just have an extra knob to pull/push.
182s are great machines. They can haul a huge load at high density altitudes, far more than the handbook suggests, or so I have been told
. You should be checked out in a couple of hours, and some places will hire them to you like that if you have 100 PIC. Try a few places, VGT is one of many in that area.
Looks like they have got a lot more expensive since I last looked!
Loads of fun to be had, don't worry about the LAS class B, request a full stop on the runway that parallels the Strip. Great view off your right side on final.
