It's great to have ppl like your family willing to invest in badminton. However, it takes more than 1 company to promote a sport. The problem is the lackness of "root", and the government don't really support it. Therefore, it lacks talent from the younger generation (most players are 1st or 2nd generation immigrants), and the media treated it as a joke. I wish your business to have a great success, but it definitely takes more than a few gyms / shops to promote a sport.
