This has been addressed a little in the Corporate section. But you have
Ameriflight
Salmon Air
Air Med
Life Flight
Million Air

Also there are some private flight departments and other operations at SLC intl. Don't know much about OGD or PVU, as I haven't been there in a long time. If you're looking for time builders then Salmon and Ameriflight would be the places to look. Salmon probably required the Pt 135 PIC mins, AMF since they only have turbines probably at 1500TT.
