Find an entrepreneur that has already done what you want to do by using a more proactive approach than posting to a forum like searching the web for a similar company, small or large, that doesn't compete in the same market as you.
Learn who the owner/founder is and call them or email them.
Tell them your story and make sure you let them know you want to be considerate of their time.
Ask for no more than 2 or 3 minutes to ask them your most pressing questions about your venture.
You may be surprised that they'll talk to you for an hour.
To success,
