The travel opportunity might be a way to get your foot in the door. I've talked to many people who said they were offered a job at the hospital they were traveling to 95% of the time. If you can take a travel job in the area, get offered a job there after (since they know how you work they will want to keep you on FT), and then move, that might be your best chance. Getting a job in SF (and Cali in general) is so hard. Best of luck to you.
