Business Plan for ZON PRINT FACTORY

I own a digital printing business and I print everything from t-shirts to signage. I want to start a brick and mortar store and a mobile printing lab, that has the capability to print custom items on the spot. I will carry an in house inventory of t-shirts, hoodies, polos, etc... Also, offer a wide variety of promotional products via the ASI platform. I need a business plan for working capital and securing a building and mobile bus with conversions.
