My experience tells me that you need to show the church that what you are asking for is needed, necessary and will benefit the congregation more than you. A good connection or two never hurts. Always have a plan the finance committee can look over.

Using your own equipment comes in handy on a special needs basis, but unless you plan to use it exclusively in and for the church, leave it home and find another route. I have a lot of personal stuff at church, but I've been in the same place for 38 yrs. It's stuff that was sitting around the house doing nothing and the needs of the church met my need to find a use for it.

Use the CM-30's for a few weeks and show them what a difference they make. Talk it up. Then present two or three alternatives they could afford or want to afford. You must convince them music is an integral part of the "church".
