I have an idea that I think people will love but I do not have contacts to make it happen. What can I do? –@wikibacher
I will tell you the exact same thing I did that worked for me.
Make a list of 20 people in your industry that you don’t know.
Tell them your idea completely. Don’t leave anything out. Be succinct so you don’t bore them. Flatter them a little.
Then tell them you can do the idea FOR them.
See what happens. They won’t steal your idea without you. They will contact you with questions, ideas, and maybe a meeting setup.
If one of them respond then contact twenty more people. Even write your idea up in a popular blog. Whatever it takes. Get your idea out there. Someone will eventually ask you to do it.
