Start popping out the babies now, that way in a few years you'll have enough child talent to produce your own modern version of the Brady Bunch, only the West Covina version where the mom is an ex-chola from Montebello and the dad is a rich writer from the West Side. He was finishing his journalism degree at Occidental college when they met at a local roller rink. You will need nine to ten units of child talent of varying ages to pull of this casting feat, and the more of them that come directly from your own family whom you will not have to pay the better.
Child talent may seem like its pretty easy to come by, but people want contracts, regular meals, worker's compensation, all these things just end up being a big pain and a major chunk of your production budget, so get your wife off of the birth control, and start churning out that child talent now! If she's unwilling, don't let that stop you, you can always have more kids with someone else. There are plenty of attractive women of child-bearing age out there! If she's unwilling to support your dream, you don't need her.
Imagine, only a decade or so of dedicated parenting and child talent nurturing and you could be in position to produce a great new hit television series that will last in people's memories for a lifetime. Make your house a child talent R us depot, where a couple kids at a time can be farmed out to various acting and modeling gigs, earning enough to pay the mortgage and keep the family in vegetarian hot dogs and soy milk!
