This is a very good idea, however, writing to medical companies, hospitals, doctors etc. will have very few results because there are few doctors and researchers willing to go out of their way for something as "unimportant" as BO, which cannot bring them the fame and wealth they dream of. You need to include some sort of mention regarding the material gains they can make because people who have it are already spending so much on alternative methods, and if a real cure/cause is discovered, they will be more than willing to pay to eliminate this problem.
Unfortunately, in today's world most doctors etc. will not do something like this purely out of the goodness of their heart...
