Apart from a brilliant idea. you need a professional business plan to turn your idea into successful venture, especially if you are talking to a bank or an investor.
I will write a professional business plan for you including cash flow, sales projections, break even analysis, marketing model etc.
I can even include a WBS (Work Breakdown structure) made on MS Project along with a gantt chart schedule if you need!
Just share your idea with me and let me turn it into a solid plan for your investors!
