Before the medic1 hiring process, our starting medic pay with no experience was mid $17/hr putting that around 44k per year. Wilco's starting pay is closer to 50k per year right now, but their schedule is 24 on 48 off. Comaparitively speaking due to a lower cost of living, ATCEMS and Wico are two of the higher paid 3rd services in the country where you do not have to be a firefighter. However, as far as ATCEMS goes their may be some big changes to come since we are now civil service, including the possibility of merging AFD and EMS.
Sounds like the writing is on the wall. Hopefully the merger doesn't happen. The EMS side almost invariably loses it's identity and share of resources. Just ask any FDNY EMS employees who were OTJ before the 1996 FD merger. I have two cousins that left there a few years after that debacle.
Here's one disgruntled member's blog on FDNY EMS:
