It's pretty loose. Each field crew has a foreman and 3 or 4 guys on it. On bigger jobs the crews sometimes work together. In the office I've got Paula who's the office manager, and 3 people working for her doing the general customer service, bookkeeping, and online presence. The sales guys pretty much work on their own. They coordinate with Paula about some stuff, and they come straight to me with other stuff. We've got a couple subcontractors we use as well. One did our website and helps with the more complicated web development stuff, and the others we bring on to help with the installs when we get really busy.
