To truly motivate someone to do what you want them to do, begin by putting yourself in their shoes and figuring out what they want or need. If they can benefit from your product or service (assuming you commercialize it) then you already have something to offer. For example, free or discounted usage of your product or service for a limited period of time, access to data you collect in surveys, financial reimbursement for their time, etc.

I have had a great deal of success with this approach and highly recommend it.

And for those people warning you to be concerned about other people stealing your idea, don't listen to them. Ideas have no value; its the execution that gives them value. If you're really concerned, file a provisional patent application. But whatever you do, don't let this amateur concern delay your progress!

Hope this helps. Please let me know if I can be of further assistance. As always, I highly recommend using our framework to navigate the idea development process available through www.ideaessentials.com

Thanks and best of luck!
