Making lemonade??????????????????????…

hi I am 12 and I am living in France. I am trying to make a lemonade stand, however here they don't have lemonade stands and that's what I want to do. Anyway I can't buy frozen lemonade either, so is it easy to make? Where should I have it? my sidewalk fits one person on it. Should I do it at my school, when school starts in September, or will it be too cold?Nobody really walks on my street so I don't know know who I would sell it to, and I can't go into Paris for it. What do you think?
