I believe the pilot you talked to that works there would be the best bet for inside info. I don't know too much about LifeTeam (MWCA's EMS operation), but I know they run a PIC/SIC operation, so even if you don't meet the Captain's mins, maybe you can get on as an SIC.
As far as an EMS job goes, I can tell you that I love it. It's the most interesting job I've had, and it's got the best schedule that I've ever had too. It gives you a good feeling knowing that you're helping someone in need. Plus, getting priority into everywhere (most of the time) is nice too!
