I have a single paragraph that I send to contractors looking for subs. It basically just says I have experience and tools and that I'm clean-cut, honest, professional, don't drink or smoke, have a driver's license, reliable transportation and no drama. Because that is exactly what they are looking for.
You put a grand down on a nice white, ten-thousand dollar used van that doesn't leak oil, maybe $2500 for essential tools and machines, etc. and a Home Depot card. Then just show up and do what you were hired to do. It's as simple as life can be. Being a contractor is for people that need to work but don't want or can't handle a job - that's all. It's a lifestyle for borderline personalities.
Seems easy enough yet many find it difficult.
