RE: Need advice on finding a person to train me
Every club usually has an instructor or two. If it's an AMA Chartered club you'll need an AMA License to be able to fly there. If you don't have AMA, a club Intro Pilot can help you out. If you don't intend to join the club, I doubt much help will be handed out. There is no charge for club instructor help.
Perhaps you can check with your LHS and they can direct you to someone that would go to a park to help you.
