If you follow the path I took to get backing be prepared to state your case over and over again . Get up every day with a new found enthusiasm for what you wish to accomplish.
Find someone fairly local who did something that everyone else thought was totally nuts or wrong but succeeded wildly, they will not only have the money to loan you but also the mindset that it can successfully happen. My investor flooded his cornfield in 1949 and it became a lake offering swimming, camping, and expanded from there.
I also was 38 years old and had worked like a dog long hours for the previous 15 years as an adult so I had a good reputation to rely upon.
To make this all work , you also will have to put in long hours of concentrated effort towards this dream of yours.
Anything worthwhile really never comes easy or is just handed to us.
Money or situations in life handed to us almost always fail because we don't appreciate the opportunity enough to make the effort really needed to make it work.
Possibly everything else in your personal life will have to be asked to sit in a distant backseat for many years .
Or you could win big in the Lotto? Or some wealthy relative could hand you the money then forgot they did that?
I have known some people who waited 30 years for a certain relative to die and leave them the money they needed for something, it would have been easier to just work hard, in my opinoin.
This is all I know about achieving a dream.
It worked for me because I worked. Still working at it everyday.
20 years now.
