You aren't related to "Keith Stone" are you

Sorry, couldn't help myself.
Serious note, another resource are aircraft management companies/individuals. I ran into a guy several years ago out of the Milwaulkee area that was managing 6 different companies aircraft, and he had a handful of pilots that worked for him. Sorry I can't remember the name, been awhile.
Honestly, I think these guys are hit and miss as anything else out there, but it could just be your shot getting back in.
