Good luck dude. If you find something that pays better than a regional in SoCal with your time, I'd be interested to hear about it. I'd recommend getting another 100 hours and applying at Amflight, though the pay there is no better than a regional. Most of the jet charter operations (Clay Lacy, etc.) involve some kind of PFT, and/or have miserable pay and work conditions. There's a reason most of the CFI's in SoCal end up at a regional. Most corporate gigs require much more time and/or excellent contacts. Assuming you don't have those contacts, why not consider the regionals? If you're in it for the money, you may need to look in a different industry in SoCal, at least with your quals. Good luck.
