Start with the basics. Get your own insurance. Check the city hall in the city you want to do this in. See if there are any zoning issues, if you can put games there. And find out what licenses you need. May be on you, your business, the game and location.
Quoted from V8haha:Not expecting to make a lot of money or any for that matter!
That's a good plan for what you want to do.
