Looking for a single parent with a child approx. 9-11 years old

We booked flights to Egypt for the autumn holidays (RLP), and wanted to see the pyramids during the 2 weeks (approx. 2 days in Cairo) and spend the rest as a beach holiday in Hurghada and/or Marsa Alam. Preferably with snorkeling/diving in the house lagoon. We'd like some action, regardless of the area. Basically quite open to everything. As a solo traveler with a child, you usually only meet families or couples with children, which is absolutely fine in principle, but why not specifically look for someone in a similar situation? My son is 10 years old and is in the 5th grade of Gymnasium.
