need help with executive summary

I found this on the web, and it covers pretty much what needs to be covered. This is not gospel. But it’s a good place to start. It at least gives you the points to highlight and reference. Remember your goal is to give them a professional format to review. Tweek it as necessary.
1. The problem and your solution. These are your hooks, and they better be covered in the first paragraph. State your value proposition, and what specifically you are offering to whom. Skip the acronyms, history of the company, and the disruptive technology behind your solution.
2. Market size and growth opportunity. Investors are looking for a large and growing market. Spend a few sentences providing the basic market segmentation, size, growth and dynamics - how many people or companies, how many dollars, how fast the growth, and what is driving the segment. Skip the comment that you are conservatively estimating your penetration at 1%.
3. Your competitive advantage. Identify your sustainable competitive advantage, like unique benefits, cost savings, or industry ties. Don’t kill your credibility by saying you have no competition. At minimum, you compete with the way things get done currently. Most likely, the investor has already seen multiple plans with similar solutions.
4. Business model. Who is your customer, what is the price, and how much does it cost you to build one? Do you now have real customers, are just starting development. Outline your sales and marketing strategy (direct marketing, sales channel, viral marketing, and lead generation). Identify key quantities, such as customers, licenses, units, and margin.
5. Executive team. Remember that investors fund people, more than ideas. Why is your team uniquely qualified to win, and what have they done before? Explain why the background of each team member fits, by naming roles and names of relevant companies. Include outside advisors if they have relevant experience.
6. Financial projections and funding. You need to show your summary revenue and expense projections for three to five years. Investors need to know the amount of funding you are asking for now, and what they get. The request should generally be the minimum amount of cash you need to reach the next major milestone in your plan.

Cory has provided a very effective list of Executive Summary inclusions. I just wanted to add three additional suggestions:
1) Summary Page--Most people don't like to read a long ES, so page 1 should be a summary of your summary. Tell them what you are going to tell them and really hit the highlights on this first page. The remaining information is the support documentation.
2) Pictures Sell--Include visuals on the property and neighborhood, a map, a google earth view, and make these color wherever possible. These make the property more real and tangible. Put captions below the pictures if needed to explain or point out something, people will flip to the pictures to help convince them of the validity of your project.
3) Accompanying Articles/Authorities--Articles on market conditions, local expansion plans, and local or regional economics or demographic factors that influence the property can be attached at the end of the ES. If the article is authored by someone with a title, or an important local or national figure is quoted, try to include a picture of that individual with their name and title below. This makes your documentation have a more authoritative read.
Bonus suggestion--If the ES will be presented as a hard copy, spend a little for a nice presentation folder. Humans have five senses, you are more likely to get a yes if you appeal to as many of those as possible.
