Business Plan for a Game Application

I am planning to go to investors to raise seed funding for the Game Application that I am developing. I have written the basic business plan, however, I would like some one to give a professional touch and add / remove any stuff required to dazzle the investors.

I really hope that it will not take much time for an experienced person.

I will need it by the end of next week: 19th Feb 2011, so, I want to meet the person in London and get it done in a day - If it is possible.

I will need further assistance and continuous support in the future as well.
