Any advice for urgently rehoming (USA) my dog due to extreme change in life circumstances?

As title says my life has changed drastically in the last few months to the extent I cannot continue to keep my dog. I am heartbroken but there is not really another option at the moment. I am willing to provide financial support if necessary to make the rehoming easier but I just don’t know who to reach out to with such an urgent request. Any advice would be appreciated, but I really don’t want to send him to a shelter. We are located in LA. (This isn’t an advert for my dog).
