Hi, I work in an out patient surgery clinic in the east bay.
Where, if anywhere have, you applied? I don't know if where I work is hiring, I am per diem per my choice, they may hire per diem staff....it could work into a full time job for you?
I know they like staff willing to work late shifts. It is out patient surgery but so many days run over time into the late evening, there is always talk about hiring someone (again maybe per diem) to help with occasional busy/late days, to 9 - 10:00 pm on occasion. Again get your foot in the door, these "yucky" hours could eventually change to more regular hours.
We also have occasional over night patients, from twice a month, to 2 - 3 times a week, it really varies. Again a way to get your foot in the door if you were willing to take this shift on occasion. (I would be clear that you are willing but if you don't get moved to "days" eventually you will look for another job).
We also do GI procedures. And there are some GI only clinics in the area. Have you applied there? Pre-op and post op GI clinics are similar to out patient surgery.
