All sounds very promising.
The last airline I worked with who gained approval, the emergency EVAC was performed in the morning, FAA guys had lunch, then came back with the certificate, proving runs were performed almost immediately.
It may be slightly different for a 125 flag though.
Be warned the emergency EVAC is a well rehearsed drill but if anything goes wrong, just one minor slip up and the FAA has the right to decline approval until a rescheduled successful EVAC drill has been performed. That can be up to three months, depending on how user unfriendly your FSDO is !
