Guys I am starting up an Electrical Contracting Division of our current company. We currently do lighting control, home automation, home theatres etc.

We are hoping this will give us an avenue into more of the builders market being able to combine high and low voltage with the benefits of the things I mentioned above for custom builders and home owners. I will need to hire a Master and helpers.

My questions are:
How much capital do you think I need to start with?
How long do you think it will take to have the electrical side earning its keep?
How much stock should be kept in the warhouse or should it be picked up at the supply house?
What should I pay for a Master, Journeyman and Helpers?
How should I charge, by the square foot or by the outlet?

Please comment with any questions or directions you think I should take. Thanks for your time in advance.
