Jen, I saw a trailer set up as a DJ booth on craigslist for sale. It had what looked like a giant CD on the side of it that you could spin around by hand. Now that gives me the idea that what you could do is make a wheel like that to put on the shack and post things on it like wheel of fortune. Wherever the needle lands is the prize you get ie.. Buy one get one free or half price, buy one get one free on your next visit etc. Each kid say 8 or under gets a spin or one spin per family that comes to the shack. I believe in aggressive marketing like playing some Hawaiian music through a loud speaker, have your kids out there eating a shave ice and having a good time, It'll draw other kids over. Idk, it's just a thought. With some bright colored paint and a little plywood, I think it would be a great marketing tool. For a thirty dollar investment what could it hurt? Plus it has the game concept and you know kids love games and winning stuff. Another idea I've been working on is doing private birthday parties, corporate events, etc. We have a lot of factories around here and they all have a field day where all the employees and there families come to a local park and have a big event. They give away door prizes and stuff. I think it would be worth while to get in touch with the places that do things like that and contract your shave ice to be served there. You can charge the families, or set up an hourly contract rate with the company for unlimited ices, just however you want to arrange it. The factories around here have several hundred employees plus generally an additional 2 to 3 people in the family. That makes for around 1000 people out in the sun doing potato sack races and all sorts of things to keep the active and hot. A shave Ice would be just the thing to cool them down. Food for thought.
