Where to work per diem or registry in San Diego?

We've been in San Diego for about 4 months now, and my husband would really like it if I would pick up at least one shift a week. I was wondering what are good companies for LVN's in this area. Ideally I'd like to work only one night shift per week. I had applied to Sharp for a per diem position in the ER, but they wanted someone to commit to 3 shifts a week - that sounds more like full time than per diem...lol. Can anyone recommend a place they've worked registry/per diem and had a positive experience. I have 2 small children, so I really need flexible hours. Thanks in advance. I'm in East County.
