I think that you'll find, after doing more diving, is that the difference, in safety, between 40' or 50' and 70' or 80' isn't all that significant. If you do want to stay shallow, many dive ops offer afternoon dives that are often not as deep as their morning ones. Hiring a private DM is an excellent decision and you can tell your DM, if you wish, to stay above 50' and they will 100% accommodate you. Sharky's is a great option as they will provide all the gear you need (minus a computer) for free. Walter (or favorite DM at Sharky's) taught my novice 12 year old daughter to dive. I was so overcome with emotion that I hugged him, mid water column, and I must have had a very bad mask leak as I couldn't see much
