There are regional sub-forums here, just scroll down
You should look into the SoCal & the Florida regional subforums (I think there are several representing different areas of Fla.). Post in there, you should be able to find buddies.
I also use the Meetup.com website and app to find buddies & arrange dives. There are several Meetup dive groups up here in NoCal, I would imagine there are several in the SoCal area. Sometimes folks arrange group dives that are newbie friendly too. I also used Meetup to arrange a local buddy in Oahu, you can do the same for Florida.
There are several Monterey area facebook scuba groups, there are probably some in SoCal too. I find buddies that way too.
Enjoy your diving!
