At the end of Shemone Esrei, where we insert a pasuk that corresponds to our name, would someone with multiple names (e.g., ELAZAR MENACHEM MAN), say a single posuk or multiple pesukim?
What you are missing here is the pay issue. Morahs are paid poorly. If you want commitment, it comes at a cost. If you pay pennies, you can not expect a commitment from a young lady whose first responsibility is to get married. If you pay respectably, then you can make some demands.
