The tides at the St Andrews State Park (shore dive - jetties) would mean early starts to get a dive in at high tide. The dive operation in Panama City beach I would recommend is Diver’s Den (they’re on the web) both for fills and they do have a charter boat as well. The boat crew (captain and dive master) are great and make the experience really enjoyable for new divers. I think they run two trips a day on Saturday’s and Sunday’s. I may be available to dive at the weekend but I’m not sure at the moment.
