Thoughts on hiring experienced workers ($$$), or newbies ($) for a new/small business

In almost 20 years of lawn care maintenance I have trained, and i have worked with other well experienced workers. With anyone new ive trained over the years, I start with communication, putting a tool in their hands and then shaping their movements with quality, and adding speed later. With experienced workers, its much easier to make simple requests as a leader, i.e. "Do me a favor and raise your trimmer a bit so you dont burn the grass."
