Having your own store... making your own hours or hiring some help... selling whatever you want: extra weapons, potions, spell books, food, etc.

Use the money you make to open more stores.

Any thoughts?

Awesome Idea, it'd be nice if this would become a reality. Created a building in skyrim is easy but adding all that to the game would be difficult.

There is a similar mod available for Oblivion. It's called "Trade and Commerce". Would be nice to getting this transfered to Skyrim and then maybe extended a little bit
