How do i get an investor to invest in my Multi-Million Dollar business idea? PLEASE HELP?

You'll need to sit down and write a complete business plan. The plan should include costs to set up the business, a realistic estimate of your cash flow and profits (it probably won't be as much as you think), how much cash you will need to get this off the ground and how much cash you intend to put into the business (or your intended role in case you aren't putting much up).
