Honestly, do you have a contractor friend who can do this house with you?
One who has the credit with the supply houses to get the material? Experience doing these installs?
You'd be surprised at how much this will affect your service business. This house will take you 2-3 times longer than you figure.
If you want to do it on your own. Go to your local supply house and talk to them about credit. Get ready to work 18 hour days for about 2 months. 8-10 on this house, the rest on your service customers (if you let them down, they will do somewhere else)
Get a sizable deposit before your start the project (1/3-1/2) this will give you some working capital.
Bust your ass.
