Royce makes a great point. The lament of many successful businessmen is that they no longer get to do the thing that they love; they're always teaching someone else to do it for them. In this way, they become a force multiplier. They set up the business, train the personnel to do the work, acquire the work that keeps the crews working, buy more equipment to start more crews, and keep growing the business.
Reg Coates seems to think trying to go big might be a mistake, if I'm reading him correctly. He wonders whether or not the owner ends up any further ahead financially by having lots of employees, and high overhead.
To me, though, you seem like the quintessential entrepreneur. On fire; champing at the bit. You are so young to have acquired such gear, too! High energy level due to your youth and just your own physiology.
I'm thinking you need badly to talk directly to Brian Bixler, of Bixvid fame, if I'm getting the spelling right. He seems like he might be just like you, only he's a bit further down the path than you are right now. If he were willing, he might make a great mentor for you, even if it's just long distance, over the phone once in awhile.
The big thing to try and find out from him is how much he likes or dislikes being out on his own.
I wish you good fortune whatever direction life leads you.
