Since this question is from a year ago you most likely have made progress towards launching your idea. However one of my recommendations would be to partner with a hospital as a beta site. That has been a proven and low cost entry for many of my clients and with my own company. Pressure ulcers are very problematic for patients their families and costly to hospitals so an innovative idea is necessary to solve this problem or make it better. If you would like to learn more I am available for a phone consult.
