I am curious about something. I have a site idea that I think is pretty good, but I don't want to actually put the effort into building it, getting the graphics, etc... simply because I don't know if you have to get actors/actress's permissions, etc...

Point is, I have a good site idea, but I want to know is it possible for me to make money off of it simply because its my idea but I won't be actually creating the site or videotaping any of these people.

I know that is quite vague of a question.

More or less, can one make money in this industry with only an idea while others make that idea a reality?

Thanks
