Where do I find a cleaning kit with contracts, leads, supplies, etc.? -

you can buy a janitorial company that already has accounts, complete inventory and contracts in existence or like so many here on answers, you can probably find them the same way so many are looking to find a way to make money sitting in front of their computer in their pajamas all day.

You won t. You ll need to figure out what you need to buy and buy it. You might find sample contracts on the internet, or might want to consult a lawyer. You ll have to generate the leads yourself.
