What is the key to securing a large investment in a project? How much should I offer the investor in return for his risk?

Let's say all of the following conditions are true:

• I have the connections needed to get audience with multiple multi-millionaires, although I, myself, am not one.
• I have, in concept, designed a product set that will allow me to sell computers with 2x the power for 1/2 of the cost, to anyone who has access to 3G+ internet, and this performance/cost enhancement will remain accurate even after years of technology advance.
• While further detail can't be given, assume, for the purpose of this question, that the above factor serves as only 30% of the product's full feature value. This product set includes other never before produced features that increase the value, but have not been included in this question for simplicity.
• I possess, in great detail, documentations on every aspect of the development stage and can explain fully every step that needs to be taken for each feature's development within this product set.
• All hardware is modeled in CAD accurately, and experimental concepts have been prototyped and tested, although I need heavy funding to produce the full product prototypes.
• I possess professional graphic presentations that present this entire project neatly and beautifully, showing the stats, necessary funding needs for each specific stage of development, and a business model for the production and sale of the products.
• I've calculated the profits of the sale of the product to be $10 per user/month for the first 3 years and $40 of profit per user after 3 years, resulting in $1mil USD per month profit with 100,000 pre-3-year users and $4mil/month per 100,000 post-3-year users.
• The project's total rounded development cost runs at 4 million dollars, which will support a 2-3 year development phase and all legal fees needed to heavily protect and market the idea.
• There are many advanced program features within this product that will allow the project to stay far ahead of anyone in upcoming years that attempts to run a similar venture.
