Please don't go running out there and drop a ton of cash for a type. It'll be quite useless and could even look bad on your resume. (Ps. 1hr in the sim for a G5 is about $7000)
Anyway, I agree with some of the posters here. You're young and free, not supporting anyone yet, and feel the urge for some adventure. Get out there and go for it. You have more time than a lot of rookies who go out there looking for jobs.
If you've been researching the subject I'm sure you know more about it than I do, and also know you have to make the trip out there and hang around before finding a job, which is pretty scary in itself.
Check out a series called "Bush Pilots" (on youtube). It shows a few pilots doing just what you're hoping to do.
Good luck
