What about the 1 to 2 guys you will hire? Do you have funds to float them 90days? Wages, W/C, your match on taxes? Are these even things you have looked into? Do you know the true cost of running employees? Getting contracts like these isn't just about what equipment you run. You are competing against a BILLION dollar company. Do you know how many zeros that is? Another word of free advice I learned a long time ago, you need to know when to pull the trigger on a job and when to walk away.
