You gain investors by making sure you have defined and validated your market opportunity, tested each one of your assumptions, developed a strategy to reach the goals and tested that, and reduced all the possible risks to an acceptable level. It makes no difference whether it's in dentistry or farming, investors all want the same thing...a sure thing with no risk. The closer your personal efforts get you to demonstrating a proven scenario, the more likely someone is to join you in the lowest-possible-risk environment. The more risk you have, the more unknowns you have, the less work you did to validate your plans, the less likely anyone is to give you money.
How do you know it's $2million? What is this money for? What have you tried so far? What amount have you personally contributed? These are all very basic questions an investor would ask, among many others.
There are already companies doing what you propose to do. How are you different? Are you competing or differentiating? Why that location? Couldn't you do this with lower expenses in a different location?
If I don't stop, I will think of fifty more questions.
Create a competent business plan. That is the simple, non preachy answer to what you are asking.
