The company I am currently with started with just the owner, his friend and his friend's son. After I got hired I was the main full time employee along with one groundsman, and he had a small pool of 3-4 other ground workers he could call to come in as needed. Now we have a crew of 4 full time employees (2 climbers, 2 groundies). I plan on hiring one part time employee when I start my company until I am busy enough to offer full time work for him along with 1 other future employee for ground work.
