One strategy would be to find 20 minutes or so to write up an email asking "Do you have any carriers willing to write homeowners at [address]?" and fire it off to the top 5-10 independent agents you were able to find on Google, and then you can sort through responses when you finally have the space on your plate.
Best of luck! This is a crappy situation to be in, and I'm not sure it was really anyone's fault other than humankind's collective fault for climate change. The CA Department of Insurance has long seen their role as protecting the little guy from big bad insurance companies (admirably). The problem is, there's now no way to comply with DOI requirements AND make money, so carriers as for-profit entities are opting out (which is also rational on their parts).
