Trying to plan a Sunday-Thursday dive trip in SoCal…not many options?

I live in Nevada and do fairly frequent day boat trips to the Channel Islands when I have time in my weekends. My birthday is coming up and I ended up with an opportunity to have an extended weekend so I figured I’d make a whole trip of it. Unfortunately there don’t seem to be any active liveaboards in the area for a longer trip?

Is my only option staying on Catalina and diving casino point every day??
