We are going to organize dancing performance in a town hall theatre. 
I would like to get more information about how to organize the event
and set the budget.

We have already booked the town hall.  The performance will be live
dance and music performance for one and half hour.  My responsibility
will be the general coordination and promotion.

The followings are the quick check list of my role:
Stage Performance:
 - Secure the travel and accommodation of the performers
 - Hire a stage manager to arrange the sound and theatre effect
 - Logistic for the shipment of the dance clothes and stage settings
Exhibition of sample dance clothes and cultural items outside the hall
 - Set up booth for the exhibition
 - Assign volunteers to stand by the booth
Promotion of the Event
 - Design poster of the event
 - Print the poster to display in the location
 - Arrange local newspaper and radio to report the event
 - Prepare gift for the honor guest
 - Food and refreshment for the volunteers
 
What I need is a more comprehensive checklist and a better way to
organize my work.  And I need some suggestion/information to do the
estimation of the budget.
