As lugnut says, you will need to get a significant core group of people to help out. You will need help designing stages, building stages, checking people in, acting as an SO and ASO, scoring, and tearing down. You will also need some funds for target stands, targets, props, etc., and you will need some place to store them securely when not in use.
You can start small, but you will need a core group of committed people to get it off the ground.
