It's important to set up a [support] team around you. I'd suggest seeking out lawyers or solicitors  who deal in network marketing, as they're very versed in all the laws and how that affects [your business.]. There are also accountants who specialize in dealing with homebased businesses specifically in the direct-selling industry. They will be able to advise you of commission structures for your business.

Sorry i could not be of more help.
