I’m thinking of partnering with a colleague to hold a three-day challenge that leads to sales of training and products for her business with me taking a commission on those sales. She has the presentation skills on her subject and I have some marketing and tech skills to combine to her skills. Seeking advice for a low cost platform where we can host this challenge and develop a community that will grow when this beta-test is repeated quarterly or bi-monthly. Any advice on any of the above?
