Pacific Wings has no corporate flying. The Florida flying is charters down to the Carribbean in C208's. One thing I can assure you of though is that if Pacific Wings did indeed have corporate flying, part 91, it would be FAR WORSE than the scheduled operations. Remember, there are no duty/flight time limits in the 91 world.
Are you having problems finding work as a SIC under 135 with less than 500 hours? 500 hours is the minimum time for a VFR captain.
If you're willing to relocate try applying to Mokulele Airlines in Hawaii, they'll take you with 250.
