What's the best Habitat business for you to start?

Let's say the first Habitat is going to open its airlocks in 6
months. All that is there is a pressure shell, an ecosystem, and
some roads.

All the houses, stores, offices, and exterior factories are yet to
be built.

You're an entrepreneur and are considering starting a business in
orbit.

What do you think will make you a fortune? Building supply? Bakery?
Cutlery? Furniture? Fiber optics? Plasma TV screens? Clothing?
Restaurant? Bicycles?

What factory or store or service would you start?
