To answer your actual question, unlike literally everyone else in this thread has done, if you're a reasonably smart guy, you can learn Maya or Blender or something like them in a month or so (much less if you know other 3d packages,but you don't), and then it'll take you another month or two to reach PSX level modeling, counting good edge flow and textures. If you are very smart or work obsessively, you can do it in less time. If you are an idiot or a slacker, it will take much, much longer, or you may not ever get there.
Get a good basic tutorial series for whatever program you are going to start with (I honestly recommend either Maya's student license or Blender so you don't have to drop a bunch of cash before you even know if you like it). I think Lynda.com
has a free 10 day trial right now, and I personally really like their "essential training" sets for learning new programs. Those may seem overwhelming at first for a newbie though.
DO NOT try tolearn ZBrush first. I know, there is a fucking ton of awesome shit made in it, and more comes out every day, but learning ZBrush first would actually hurt you ability to learn the base packages first, imo. It's just so different than anything else out there...
Anyway, good luck OP. Don't let any grabassery you read in the threads here derail you, put in the time, and learn from everyone you can.
