By a production house I really meant production company, is there a difference?
What I mean is that he can hire a director, DP, crew, etc for Apsiring Mogul productions and then produce a story that he likes.
He could pick a big annual film market and go there every year for the next 8 years or however long he is going to wait until his career change.
And then when he picks a book or writes a story, and hires people and makes it into a movie with his own money he will already have a relationship with distributors. Even if he doesn't make all of his money back, making back 80% of your money or whatever is still great compared to losing all your play money. lol. and most importantly it would leave you with enough cash to make a second movie using all the experience you just bought yourself.
