Business plan for raising funds

I have been in business for just over two years as The Divorce Negotiator. The business has performed to my expectation but the interest I get from outsiders has made me see that there is so much more potential. Within the next two months I will be franchising the business but the figures for Europe and USA show me I should go global now in this window of opportunity before others copy the idea.
The divorce business around the world is over a 10 billion pound industry. I cannot do this alone and need funning to hit this hard. I need a good business plan to show to potential investors. I have no idea how much I need. I have no idea how much I am prepared to give away for it. I am good at my business and do not hav time to do more market reaserch than I have already neither do I have time to research what, where, when and how. But with help and an excellent business plan with you doing that research. My exit strategy is 5-7 years.
Can you help me?
