First thing you would edit.
The name where XXXNPCNAMEXXX for the hand in person. it it occurs twice.
Second.
The XXXTRIGGERWORDXXX
Third.
the XXXITEMNAMEXXX
Fourth.
the last Delay before loop has 15m that's how long you would set it for the quest to loop. the one im doing happens to be 15 minutes.

final notes.
this npc is also the person that provides the quest. it works with more than one person based on your edits.
this is the first version and it is very basic.
and i give anyone permission to use cut chop or snip it apart.

cheers
