They pay around 28k/year on 99 runs. You'll probably be cross-trained on the 402 (or 414, I can't remember what they have). Most of the people who have worked there have positive things to say about the place. Rumor has it that the boss is the type of guy who'll scream at you to your face rather than talk behind your back, so he's pretty cool in my book.
They have a younger guy working there, PH, who seemed to have his stuff together, as well. He does some of the crew training. I haven't seen MR fly, but I've heard nothing but good thigns about the guy.
The only down side to this operation is that they only give you .5 hours from the time you recieve a call 'til the time you're wheels up when you're doing the on-demand thing. If you have a ship prepared, fueled, ready to go, this is no problem. They're worried about duty time, so I was specifically told I couldn't do this. When you're dead tired, this is a recipe for a cluster f-ck type of departure.
Summation:
Good people, decent pay, they'll look after you.
Poor QOL unless you're on a UPS route, They want you to be on-call without doing the things to make on-call work.
Overall, I'd say they're a pretty good place. Before I came to Wiggins, I was kicking myself for not taking their 99 spot.
Hopefully, this helps you out.
