While I would be happy to dive with you were I in Florida at the time and were you a newly certified diver, I would be reluctant to dive with you before you had the certification--regardless of your skill.
Since you would need to rent tanks or borrow mine, then I could potentially be held liable should anything happen to you. I am not a lawyer, but I would think it would be similar to what would happen if I as an adult supplied liquor to an underaged driver who was killed in an accident. Just a few months ago I was involved with investigating the details that led to a lawsuit filed against a person who had been diving with someone who died on scuba. In this case, the diver being sued was an instructor (as am I), but the deceased was not his student at the time. It was all very ugly. I would not want to become involved in something like that, and I would counsel anyone else to avoid the situation as well.
If you have completed both the academic work and the pool sessions, you should be able to get a referral and finish up with a local instructor in two days. Then you can hang nearby with your father while he does his dives and dive with him thereafter. It would not be much different.
