business document

my name is Abdul babtein . I am planing to start a business training center to provide businessmen consulting services to develop their capabilities in managing their businesses . To do so , I need some training tool and one of these tools is tutorial business documents such as, business plan , feasibility study , how to start a business , financial analysis and projection , ..and others .
I am holding MBA from American university . I know the net is full of such documents and some of them free , yet what I am looking for is tutorial , unique and legally give me the right to use commercially .
I can help in providing some information to develop the framework of each document . we can start with one document as experimental one .
