Today nail salons have spa chairs and I want to start a company that makes entertainment system that could be mounted to those spa chairs. The system consists of a 7" to 10" touch screen LCD and a mini computer. With this system and user friendly software, the users can surf the web, play video, music and games. Because of the touchscreen, they could just use their fingers and not have to use a mouse or keyboard. The cost for each system will be at least $400. I'm close to finish developing fully functional system. I know this is a broad and non specific question, but how should I market a product like this? Is it even a good idea ? I'm thinking maybe setting up booth at conventions and store to store selling.
