I'm in the same situation...all the way out here in San Diego. Try American, though not a dependable carrier, but the airline that will take you there. You'll have to catch a flight from LAX to DFW then MIA and then SDQ (Sto. Dgo.) or POP (Pto. Pta.) Dominican Republic. Pretty hefty price for a long route like this, however, you'll definitely find good deals.
