Which step is NOT required for contractors before starting their business?

Providing customer service training is not a required step for contractors before starting their business. While customer service is essential for maintaining a good relationship with clients and ensuring satisfaction, it is not a prerequisite for beginning operations or securing work as a contractor. The other options—obtaining jobs, hiring supervisory help, and buying equipment—are all critical activities necessary to establish a functioning contracting business. Obtaining jobs ensures that there is a flow of work, hiring supervisory help can provide necessary oversight, especially in larger projects, and purchasing equipment is necessary to perform the contracted work.
