How many dives per day?
Oh, the number is somewhat fuzzy. There are dozens, if not more, of dive operators in Sharm and Hurghada. From both places one can arrange liveaboard safaries to Shaab Abu Nuhas and the surroundings.
Now, there may be some differences between the various operators. Some may be very strict about how many dives one can do per day, others may be more flexible to each individual's needs. Most liveaboards try to allow at least 3 dives/day, sometimes more. With some operators the group goes in/out as a whole, others allow to continue according to your air consumption, some will even allow you to dive freely if they know you and/or you proove yourself worthy of their confidence.
Note that you won't be alone on the boat. There are other divers in the group (which may not be so zealous about too many repetitive dives), sometimes the boat needs to move to another location, many dives require a drop from a Zodiac/dinghy which can consume time if it goes especially for you, etc. etc.
Better speak with the dive operator, tell him about you requirements and expectations from the quantity of dives you'd like to have. Some may agree, others perhaps will send you away or recommend someone else. Who knows, worth trying.
If money is not a problem, or you can arrange a small group of divers with the same attitude you may try making a custom or "private" safari.
