I want to make an outdoor projector karaoke and barbecue food stall in the square of the county seat. Have you ever done it? Can this make money? I don't need a barbecue.

You should choose economical equipment as much as possible. Now it's best to use smart projectors, karaoke, and watch movies (including 3D). The experience is very good. Consider nuts and a projector with rice. With speakers, a set is estimated to be four or five thousand yuan.
