At church, we want to plan a summer musical conference. I need to have a proposal planned for my Pastor to look at. At this workshop I do not want these people coming just to learn songs. It is my desire to have classes set for the praise and worship team, musicians, choir directors, worship leaders as well as classes for choir members. I have a few people in mind that I would like to invite to help conduct the workshop. Besides thier relationship with God and expenses, what are some more things that I need to know in order to choose the right people?
