I would say "Quartermaster", but that's more for the military? or specifically the Navy. Hmm...
...a quartermaster is generally a relatively senior soldier who supervises stores or barracks and distributes supplies and provisions. In many navies, a quartermaster is an officer with particular responsibility for steering and signals. The term appears to derive from the title of a German royal official, the Quartiermeister. This term meant "master of quarters" (where "quarters" refers to lodging or accommodation). Alternatively, it could have been derived from "master of the quarterdeck" where the helmsman and captain controlled the ship. The term's first use in English was as a naval term, which entered English in the 15th century via the equivalent French and Dutch naval titles quartier-maître and kwartier-meester, respectively.
Quartermaster sounds more impressive than Attendant. In my opinion. ;) Coordinating tasks? Head of the administration? Yes, that is roughly what the Quartermaster do.
