Selling your own flavor?

A lot of people have their own specific flavor that they like to cook with.  Whether it is a dry rub, sauce, or spice mixture, it is incorporated in many of the things they cook.  Have you ever wanted to sell your own mixture?  Do you currently sell your own product?  If so, how have you gone about getting it bottled?  How was the process of having it done?  Please post your comments below because I would love to hear from you!
