Make sure your short term and long term objectives are clearly stated (starting capital, overhead/expenses,growth projections,profitability, revenue projections... long term and short term, etc)... You could also mention the people who are going to be working on realizing these goals, their exprience, strenghts, etc.
...also present your view of the current market, how your company plans to tackle the market, who is your target what are your advantages,.. and what kind of strategies/tactics you gonna use to capture that market... things like that
Im sure if you search for business plan on the net, you'll get tons of ideas.
