I did it for 2 years in a King Air. My progression was Skydive Pilot Cessna PIC, Skydive Pilot Twin Otter PIC, BE99 Freight PIC, B350 Charter PIC, B200 Cloud Seeding PIC, B200 King Air MedEvac PIC.
It was 4 on 4 off, 12 hour shifts. 52k/year to start, 3k raise after year 1, 401k Match, decent medical insurance. People stayed at company for a long time. Was dedicated to one hospital and we did a ton of neotatal, and lots of mountain flying, which made it lots of fun and very rewarding. I loved it.
Then, new owner took over. Pay froze, schedule got worse, 401k Match no more, and no intentions of changing back to the way it was. So, I moved on.
If it hadnt gone to crap, I would have stayed a long time. I loved the job.
So, to more directly answer your questions.
1 - get time however you can (CFI, Skydive, Ferry)
2- get freight job or some other step up
3- do that for a few thousand hours, eventually moving into turbine multi equipment, and learn how to fly and no kill yourself.
4- network, and apply to medevac jobs.
Dont narrow down a path at this point. Just work hard, keep your record clean, and take opportunities when you get them. Eventually you will get there.
PS. I graduated from Kent in 06.
