First I would verify that you are in fact, disqualified from the military, and not just going by what some recruiter told you.
Second, if going the civilian route, I would verify that you can in fact, pass a class 2 physical. You will need this, at minimum for any helicopter job,.
Then, once you've confirmed those, get the money anyway you can and walk into a flight school and don't walk out until you have your ratings. Ok that's a bit of am exaggeration. The point is, aviation is expensive, and the faster you move through the process, the cheaper it is going to be for you. Try to do everything as quickly as possible.
Once you have your Private, Instrument (yes, get it, it'll open many more job possibilities - even though you may never use it) and Commercial, seriously consider, in fact plan on, getting your CFI. It's going to be the easiest, fastest way to build time towards that first turbine job flying tours somewhere. Plus you'll learn a lot and make money while you're flying. Yes, there are other possibilities, but this is the most likely scenario that works for most people.
